Where I live and commune is, indeed significant. Every creed, culture and religiously inclined dwell in my little corner, as some would say, and I know no other place on the planet that is so multi-culturally diverse and accepting of one another. I, and my close friends just happen to work and study in the heart of the community at large. It is the perfect situation for observing human-nature in relation to the habits and traits thereof.
We have business and admin psychologists from all ends of the country (Uk) coming to enquire of me and mine, as to what it is that makes the system here so ideal, culturally, religiously, communally, spiritually and ethically.
I, abruptly, ended this thread because I don't care any more for such discussion on what is drawn from the further analysis of what was founded at the onset of civilisation, and NOT from my inquisitive psyche. I find it is pointless discussing matters of philosophical-psychology here, and it was never my intention to do so. Oh how the old forum was so simple to navigate.
Why would anybody wink a greeting at someone? Just say "Hi", what further is being communicated? When someone winks at their child, on a stage, to somehow offer support??? Do they not fear their child's confidence in said situation? Have they not considered the potential anxiety in their child's mind? The "Uncertainty factor" (doubt) is present in all. When you encounter someone in the real world, you cannot know what frame of mind they are in, until you ask or are told. It can be complicated to communicate when you, yourself are not in a talkative state. This is when "winking" becomes a universal application. Deference of eye-contact is, indeed drawn from universals. Every thing about a person gives them away, their walk, their talk, the way they sit/stand, eat, grin, lean, hold, drop, etc, etc. There's nothing new about any of this in the relative quarters.
Don't even get me started on "incoherent whistling" that'll blow your minds away.
Anyway Brooklyn, have a fantastic day, and thank you for your comments.
