Since Tim and Lynda didn't want to go to the market, Jack didn't go either. When he got home, his mother was very angry. Jack was grounded for four months. Lynda, Tim and Jack were in Jack's room.
“I don't want to stay in my room for four months,” groaned Jack.
“Maybe we could all sneak out of the window!” suggested Tim.
“Aren't you in enough trouble already!” said Lynda.

Do they sneak out of the window or not?
