I think I raised a great kid Update

My son had a friend spend the night yesterday because his parents were fighting and he got hit. My son is 17, this friend if 15. My son is a junior hes a freshman. He's in their friends group. I was gonna wake my son up for school. But I saw him in the laundry room. He was putting his sheets in the wash and his pants leg was wet. I asked what happened and he said "Kyle pissed the bed. It was an accident. Don't make a big deal or mention it to him mom". He gave his friends some clothes and even washed his. Funny when my son doesn't even do his own laundry lol but he's a good kid.

Update: So he's back over here. I went to talk to his parents but when I walk through the door they are both literally fighting each other. I got yelled at by the mom but i was able to get his things. I did try to talk to them but they didn't seem to care much when he came back. I did tell my son to tell me if he wets the bed again. My son told me not to make a big deal out of it. I said I won't but if he is wetting, especially while sharing a bed. I'm gonna get him some protection.
