I started running games for my wife and her niblings, and the oldest boy is getting into that "I'm such a rebel" phase where they think they're bad ass for taking slightly longer to do a chore than needed and say "no" the first time you ask them to do something.

He thought it was hilarious to have a character that refused to join the rest of the group, so I said "okay, you can stay at the inn if you want" and then proceeded to intentionally ignore anything he was saying or doing, leaving him out of rolls, and never addressing him.

He's 12 and started literally crying to his mother about how we're all being mean to him. Apparently "he had the opportunity to participate and chose not to" wasn't a good enough response to his mother. I stand by my choice. Although my wife managed to convince me to let him "rejoin" at the next town/session.

He doesn't pull that shit anymore though, when he's playing he's playing or he gets shut out again.

Genuine question to anyone reading: does that make me a bad DM? If so, suggestions on how to handle it?
