@Olivier5,
What also makes a big difference Olivier, is where these encounters are taking place, and also if the person in question "fits" in the situation.
I've spent a little time just now thinking back on examples of situations.
Now don't get the idea that this sort of thing happens everyday, I'm just showing three of of numerous distinct scenerios.
In one type of situation, there are numerous people around. Someone holds a door open for another, picks up a dropped item, asks if you need help getting something ackward into your trunk when you're even a little bit stuggling, etc. etc. That is a "thanks" or "yes, could you lift this end up for me and we can slide the box in that way" situation. Followed with words of thanks, then each person goes their way. In fact, I too ended up going on a date with someone who helped me in a home depot parking lot secure something on the roof of my car. After he helped me, he asked me what my project was, we talked, agreed to meet later for dinner. It was a decision on my part that he was not someone to be cautious of. A big part of it was that he didn't try at any time to invade my space in an unwelcome way, or during are conversation it was not in any way obvious he was after a shot of leg. We were also surrounded by many people. He was just being pleasant. The invitiation for dinner wasn't intrusive. I remember it was he that suggested we meet at a restaurant. So, it wasn't like this stranger was now trying to get access to where I lived. I was in control of my part since I came and went in my own car.
To interrupt myself for a moment, I just hit on a big point. Control. Not control in that I'm keeping myself from someone, denying myself. It's that one is totally free with all options at any time to stop or continue. It's the not feeling obligated under a specific situation to comply to some socially accepted "ladylike" or "gentlemanly" behavior. Or, to comply. My decision, and no one elses.
On the other end of the spectrum...but still in control. Occassionally there will be in the news a story of a rape or assault taking place while a woman was, lets say jogging in the park, or going to her car. Ok, for a moment, for simplicities sake, let's just go with a woman being the victim. Could be the other way around, but let's just keep it simple. A rapist who is a stranger attacking you is an opportunist. He wants to find a victim in rather isolated area, but not TOO isolated.
Here, I'm thinking of the times I go walking/hiking on a greenbelt that circles part of the city. I have never been worried about being assaulted on the greenbelts in question. That's because to get to it one has to walk down a steep hill, on sometimes slippery ground, depending on the weather. Once down in the valley between hills, there's a path that winds miles through forest, never closer than 3 miles from populated areas.
It is unlikely someone with bad intent would make the effort to climb/walk miles out of their way to accost someone, who by the mere nature that they are down there, is in pretty good physical shape, and more likely to be able to fight someone off. Especially in light that even though there's lot's of trees and so forth, it's mostly a case of if you can see me, I can see you and maintain distance. Also, ready made defenses all around in terms of branches, rocks, etc.
There would be absolutely no reason for someone to get that close to someone else to "just be friendly"
There's been only one time in 20 years that I felt unsafe down there, and it wasn't down in the woods. I was finishing up my hike, had climbed back up out of the valley, and was making my way through a 1/2 mile flat trail at the top of the the ridge, back to my car. 100% visibility through trees with narrow trunks set apart from each other. Looking ahead, I saw someone who looked totally out of place. No one wears jeans down on the greenbelt. You just don't. He was this tubby guy wearing of all things, jeans, cowboy boots, a plaid cowboy shirt and Stetson. I remember thinking "He looks like Hoyt Axton"...look him up. Some big running to fat lumbering ox. But big. In his hands he was, amazingly, holding this maybe 3 foot stout tree branch. I stopped dead in my tracks. I stood, made direct eye contact, waited. Now, I do live in Texas, but for the situation, this person looked as out of place as a panda bear sitting in economy class on a airplane. Long story short, I ended up giving him wide wide berth, Not turning my back on him, while he attempted to make the most inane conversation with me. I don't know if he was mentally deficient or what, but it was like it never (seemingly) occurred to him that he was a 300 pound man holding heavy weapon, trying to talk to a 120 pound at the time woman. I can't remember what he was saying exactly, but he was scary to me since I was alone. I knew this big guy would never have been able to get down into the valley without having a coronary, or be able to chase someone through rough terrain. He chose the "kinda" isolated area. One where, if he mean harm, he thought he could depend on a woman being "ladylike" and accept his supposed friendliness. ****....that.
As I was making my way around him, at one point he started to take a step forward, and I stopped dead in my tracks, pointed at him and said "Don't MOVE"
Was he looking to assault someone, or was he just stupid? I really don't care. All I know was that I had to maintain as much control over my personal situation as I could, and being a lady, or obey social norms be damned.
The men who offer help when you drop a package in front of a starbucks, or who help you get up off the ground if you've fallen down or gotten your bike stuck in the mud on a more remote trail don't scare me, set off bells, and they get thanked.
It's the men who try to "help" you when you are in that gray zone of "I'm not exactly in the middle of nowhere, but there's not too many people around either." who scare me.
If a womans (or mans) body gets found out in the woods, they didn't start out there. That's just where they were dumped.
In any event, I can get that it may be depressing because hey, I'm a nice guy, I don't mean harm. But when all is said and done, the other persons reaction to you is what they have chosen, and whether you like it or not is beside the point.
Just like someone could say "well, you should be more friendly", well, it would be totally fine to respond "you shouldn't tell me how to act because it makes you feel depressed."
Like the OP. Because of her confusion on what to say, and maybe feeling it wouldn't be lady like or friendly to say "you need to go home now" she's feeling conflicted. Why go through life like that?
For every person who knowingly or unknowingly makes you question if you're being a "nice" person, there's at least one other who already knows you are, and you don't have to prove it to them. Probably more than one, because they've actually seen you how you really are.
