Why does a hot guy sit alone?

[Smoking Gnu]

If the hot guys sits alone, and there is no obvious reason, in fact there are many obvious reasons why he shouldn't be sitting alone, then see this as an opportunity to land yourself a hot guy.

Next time just ask him if you may join him. If he says no, then you know why he is sitting alone (because he is socially inept)
If he says yes, you can start a conversation by telling him that you have noticed him always sitting by himself, and as you think he looks like a nice guy, you wonder why.

After that, well...
