Is AUTHOR wrong in the post ? POST : So, lets say shes karen

Karen boyfriend, is moving to another state, and her grandmother died about a month ago. So she started "changing her style", and colored her hair and made a REALLY ridiculous haircut. She looked like these cartoon kids w green hair. If wasn't THAT bad i wouldn't say anything. I said to Karen that the haircut was weird and she started crying and said im a idiot.

Im i the asshole?

tl;dr my best friend is passing through bas times and i said to her that his haircut was hilarious
