Debby: I'm really impressed with you. You probably don't remember, but when you were little, you were very shy at birthday parties. You would run around the side of the building and hide for the first hour. But at this party, you didn't know anybody but the birthday boy, and you just joined in.

David: I don't remember that. I think they were very impressed with how good I am at Legos. I have a lot of practice with Legos. I can look at pieces and know how they are going to fit together.
