I don't think it's possible to shame a 17 year old 4chan weeaboo friend who spends his free time posting frivilous stuff on a lego forum tbh. I mean you can give it a shot but he's still hanging around like a bad smell even after all the cringeworthy stuff he's pulled, most of which would make any normal person too ashamed to stick around.
so much respect from this
Taboo is a superiority complex-ridden steaming pile of stuffty asshattery. He needs to learn to take criticism and stop being so condescending.
I don't think a 30-year old teacher should act like this!
