If I am in a street, I would say I'd be indifferent if others look at me or not, unless of course some looked at me with contempt or stared at me. For me looking at others, however, is different, and is somewhat impolite in my mind.

My point from earlier threads, is that language could be a barrier. It could be a talk starter for extrovert people, but also could a talk barrier for introvert and shy people, like me.
