Why was his dad like this?

Anonymous
It was my first time meeting his dad & he would joke with him but pick on him in front of me & say stuff like you have to know stuff about your major sports something and was saying he doesn’t know much about each sport. And then I said he’s a cancer theyre funny and chill and his dad said “you’re a cancer? you’re funny & chill whattt” just joking with him but still… His dads a veteran and big and strong and he was giving off intimidating yet nice vibes. they’re relationship okay but you could tell he doesn’t want to disrespect his dad and say anything in a wrong way. He gave him a death stare once lol.. but he loves his dad don’t get me wrong but i was so confused
