I live in a city where it don't have a lot of bule and the few that are living permanently here are all 10-20 year more old than me.
Where ever I go I got stare.
When I take walk, there where young girl crossing me again and again with their motor for take a look at the bule.
Hear on a corner while I was waiting for my light: "Hey! Ada bule!"
That make more than 2 year I'm now in this city and it seem they start to be habitued to see me, but still....
La motivation vient en se motivant ~ Motivation come by self-motivation
First thing to do, if you feel annoyed, go and tell him that you don't like the way he's staring at you. Whatever his motivation is. You have the right to do that. Hopefully he won't bother you anymore.
So, don't think or even care about him unless you want to fall in love with that man. Remember hate and love only separated by a very thin line hehehehe...
