I look away and feel very awkward. If its a girl i for some reason stare longer.... And it becomes more awkward, then i realize im staring at her.... If its in the car i open more my eyes and stare longer and have a big creepy smile like this..
keep staring for a brief moment without expression then look away slowly. This leaves them wondering if you were just in deep thought or if you were actually looking at them. if your caught again smile. If you look away quickly it shows insecurity. The expression in your eyes says it all.
For me it depends on who it is like if it's a totally stranger then I look away as fast as I can but if it's a friend I just smile. Sometimes I can't help but stare. You just get that feeling sometimes.
I wait to see if they stare back and if they don't notice me I just walk up and ask them if its ok if I stare at them. Most of the time I get slapped or something like that, but sometimes it actually works!!
it depends if they say something say i was not staring i was merely looking there is a big difference if they just smile at you just smile back , but if they get a weird look on their face look away and blink a lot like you were just staring into space
i kind of smile but then if they are near me and like we are allowed to talk i just start a conversation because hen they think that you just wanted to talk otherwise i just smile and slowly turn back to what i was doing before... oh yeah and keep smiling until hey look away or else they know it was a fake
