I went with my group of friends to eat some sushi the other week and, when we're finished, we decide to go for a walk together. As we're walking, this girl, which I'd never talked to during the whole lunch, walks to me telling me that she thought I dressed horribly. 
"I'm not saying it to make you feel bad, I just want you to look better"
This kinda pissed me off, so I half-jokingly told her that I didn't go outta my way to let her know I though her backpack was shit. She didn't take it too well and ignored me, and a coupla friends gave me weird looks.
Am I the asshole?
