I'm usually the cynical asshole in real life, similar to the way you act on HAN. I think life would be boring if I acted any different, but sometimes my friends get fed up with the constant smart remarks and shit talking. Maybe the guy just had a bad day, and you caught him off guard?

You shouldn't have to put alot of effort into a friendship. If he's a good person, he'll forget about it at some point. If not, you don't need him anyway so bang his gf and solve two problems.
