The “contributions list” is posted and Mom was a little tired of waiting for the kids to do their chores so she just said: “We’ll have dinner when the chores are done.”
One son said, “Yeah, well then I guess we won’t be eating for a while!”
She said, “Whatever” and sat down to read her email. She just kept calm, didn’t engage in the conversation.
They did eat but about 45 minutes later than planned.
Now the kids know that when she sets a limit there’s no arguing about it.
