What's hilarious?

What kind of question do you ask if you see a group of people talking in low voices, crossed arms and serious expression on their faces?

One person in particular decided to ask this:
"What's so hilarious?"

I have no idea what in the world he was thinking. Or whether he even understands what 'hilarious' means.

To be honest, I might have responded nicely if it came from someone else but this guy is someone who brags about himself all the time. Let me repeat: ALL THE TIME! And I heard him correcting other people's language numerous times before. Really. I heard him because he was talking so loudly, as if he wanted everybody to know the other person made a mistake. Or that he wanted everybody to know that he's 'good'. Yeah, whatever.

My sister would definitely say this guy is just seeking attention. Which I definitely agree. But, tough luck, wise guy, you're barking the wrong tree. If I don't talk to you, it means I'm not interested to have conversations with you. And absolutely not interested to be corrected by your 'hilarious' smart-ass language.

So eff off!


p.s. I guess my friend found it hilarious - she laughed all the way back. At least someone is being positive about it...
