@sukaley That's nice and all, but either way, she's still assuming there's something wrong with a guy wearing nail polish, instead of just thinking "Oh well, everyone's got their own hobby."
If the dude is into fine art, he should know about paint thinners and how to remove paint.
@Revvex Not exactly. She was worried he's experiencing problems because of it, as she assumed he has a gender identity disorder. People would get bullied for less, and they know it, which would cause anxiety and stress.
