@Goatmanice,
You're young Goatmanice, you're going to see a lot of things in life that aren't the way you do it. That doesn't mean it isn't normal.
As an aside, I always find calling someone, or what they do "weird" as so unthinking.
Usually when I hear someone say "that's weird" it mostly means they haven't given it much thought, and it's a knee jerk reaction because it's unfamiliar territory.
Weird would be more like you were thinking of someone you seldom think of, and the phone rings, and it's them.
Weird actually means supernatural, uncanny or inducing a sense of disbelief. People throw that word out there not even understanding what it means.
Just another way of saying you can't be bothered to think about it. So how can you really have a sense of judgement about what it is?
Peeing or drying off with the door open, breast feeding in front of someone, etc, isn't weird.
