Ohhhh he said it like that 😕 then yea he’s pretty insensitive . That shows he’s unable to put himself in someone else’s shoes and see how they feel. He’s not a compassionate person. Now, this doesn’t mean he’s a baaad person right off the bat....but there’s certain friendships where teasing each other and being a little “mean” is normal. It doesn’t seem like you want to be in that type of friendship. It sounds like you feel conflicted....maybe next time he makes fun of them you should try to defend the person, and see if he changes his perspective...
