We had dinner last night at Chili's and when we sat down Drew told us her "giant ghost friend" (actual phrase used) was going to eat dinner with us. She asked us where he could sit, we told her in the 4th seat (where we had to move our purses and diaper bag). We asked her what his name was, she told us "Alice." And then we had to shake his hand and offer him some of our food and drink.
Her other imaginary friend is Susan from Monsters and Aliens, who is 50 feet tall and requires batteries. Every so often we catch Drew pushing a stool into Boppa's office so she can reach the batteries and put more into Susan's back.
