You’d think this guy would realize the girl he was chatting with wasn’t the same girl he works with – it’s Facebook. There’s photos. Even if her profile is super private he should be able to use the four brain cells he’s got working overtime in his head to figure out “Hey, that is totally NOT the same person I work with five days a week.”
I mean for fuck’s sake the two aren’t even in the same country – you can have half a pass since both girls have the same name, but keeping up with this conversation for as long as he did without thinking anything was amiss? Cripes.
