I take back every nice thing I said about the mom
You think sending away your youngest child because he is more "mature" is the right answer? Just say you wouldn't have known how to handle it either. If the brother was a running chaos, he should have learnt that his actions have consequences, that's real life. Instead he has mamma covering for his ass as if he was some sort of toddler. And also, forcing the young child to go to the wedding of someone he doesn't want to see just because he is family??? Are you serious? Do you even know what boundaries are? Do you know what is to respect them?
I need the uke's friend story too. I'm a sucker for the childhood friends trope
