Why do some Facebook “bartenders” get so mad at harmless comments?

This girl posts on facebook that she's held together by caffeine and I dont even remember what else she said. I respond with And? What's your point? She responds with why are you even here? Meanwhile all the other girls are telling this girl how her 3 night sleep deprived look just looks absolutely amazing. Honestly, I wasn't even trying to be offensive. They get so pissed off so easily.
