They are discussing the fact that they are both feeling bored and need to do something fun. The daughter suggests that they should have a four-some with their parents and invite them to join. The other girl is hesitant at first, but eventually agrees to the idea. The two girls leave the room to get their parents to join them. When they return, they find that their parents have already joined them.
