Would you say that he is immature?
So this guy pretended to be my friend and straight up called me a 'freak' behind my back (he screwed up, and I heard him) then when I confronted him online, telling him I will not have people make fun of my disability and calling me a freak, he denied everything (despite my friend as witness) and his replies became nothing but curses. I confronted him again, asking why he treated me like such. He got angry, growling (literally) and he said if I lost a game of rock, paper, scissors, he would strangle me with his legs. (He's a big guy) This guy is an 18 yr old man. When I looked him in the eye he looked like a 5 yr old having a tantrum and he popped his tongue right out at me. He's weird and last week he was singing Jingle Bells (badly) while head-banging to it.
