Guy-who-called-me-asshole

Mmmm... I almost forgot. Today I met again the-guy-who-called-me-asshole-in-the-train (tgwcmaitt).
So, the bastard called me asshole again. It turns out that because I reacted quite nicely the first time
he decided to insult me, now he kind of likes to call me asshole. He says it's fun he can just call me asshole.
Shit. The world's full of assholes.
