Theory: Maybe the guy in this FML is the same guy in the previous FML about the painful bumhole. That explains why he didn't sit down!

I don't think it had anything to do with how the OP's attractiveness. Maybe he the kind of person who likes their space. Or possibly the way the OP smiled creeped him the **** out.

to all you people saying "he's a jerk! he's not worth it blah blah blah" have you ever though the op is not attractive or maybe he was being polite or being shy. think before you speak. not every girls is "hot".

He was probably shy. As a person who takes the bus and is terribly shy, I'd much rather stand than sit next to any strangers, even when he's a cute guy. :T

Well, I think u creeped him out with your smile

It's those damn cougars trying to get the young buck

Damn girl yous an ugly trick!

he's prolly nervous

Men have been taught to avoid speaking to or sitting next to women on public transportation because so many women are harassed there, and to avoid being That Annoying Unwanted Guy, they might stand instead of taking the only empty seat next to a woman. Smiling doesn't help, because many women smile as a defense mechanism. If you wanted him to sit, you should have just invited him to do so.

Not personal. He probably just felt uncomfortable with the flirty smile
