Bella would like to know in advance if Trouble is liable to appear with baked goods. So she sits with him at lunch.
"Hi, Trouble! If it should happen that you come over for dinner tonight no one will make you eat your vegetables."
"Well, I did suggest that maybe we shouldn't have you over to set off fireworks, but the hills seem uncalled for."
"I just didn't want to find out experimentally how you and firework safety mix. Especially when it's my mom setting out the rules."
