I want to see peoples' opinion on women opening men. I'm talking about those girls who are complete strangers walking by but when you make eye contact, they either smile or say hi. I'm in a comfortable relationship but I experience this a lot in my university just walking around.

In your experience, are most of them just being friendly or do you think they subconsciously act that way because of attraction?

Ofcourse its attraction. They wouldn't smile or say hi to a hobo,would they ? They find you appealing.

Could be, but I wouldnt judge on this alone. Thats just being apart of society. I have female friends that say hi to old people that doesnt mean they want them. Its just cordial. But on the other hand it depends on the feeling you get when she says it. But mostly its cordial

I am expériencing this too with some girls
At Collège ,and i think its attraction but i wonder
How to deal with It from there to préservé this
Attraction ...

I think it depends on the location. I was recently on holiday in the Philipinnes, and people there are rather relaxed, and some strangers smiled at me or said "hello". But I live in the UK, and in towns and cities here, passers-by don't generally greet each other. However, at a university (or other place where lots of people attend) they might be more open towards each other, as you're all in the same tribe, so to speak, even if you don't know each other. When I've been in public places I've often had gorgeous women look at me with their eyes transfixed, and me being unconfident, I've usually broken eye contact with them first - if I could even look them in the eye in the first place!
You could just say "hi" to them, maybe have a little convo about your studies. Just keep up a friendly vibe and things should be fine.
