I hate whenever I'm looking around a room, listening to someone speak or something, and I accidentally look at a person, and RIGHT when I look at them, they look at me, and we make awkward eye contact.
Or, when you're standing somewhere, yet, someone's staring at you, but you don't know if they are or not. And, so when you look back to see if they are, you get afraid to, and don't look, so you double-take. Turns out they are because they give you that look of "wtf why are you looking at me".
