I just glance and look away. If they are talking to me then I look at them and then at the floor and back again. I'm trying to learn how to make better eye contact.
Yeah sorta feel like that when i actually am about to get engaged into some relationship kinda stuff but then my inner voice shakes me and asks me 'do I really deserve what i'm aiming at?' then i spontaneously back off from the issue with that beautiful/handsome person because it can be really painful to look at downed self of you
