It's my friend!!

It's not uncommon for me to be doing something around the house and hear Aiden in the next room talking--to himself/on the "phone"/with his friends. And every now and then he'll run past me all excited and yelling, "My friend is here!" (You see, he was on the phone talking to him and then invited him over.) And he'll actually run and open the door and talk to his friend as he comes in and takes off his shoes. Then, he excitedly tells him to come on and "they" run to the living room to play. Well, at least he has an imagination!
