I'm going to say he's advanced

Tonight a friend of mine from work, let's call her Ann, drove E and I to another work friend's party. E's a pretty big fan of Ann, and was thrilled to get to hang out with her. She's also pretty gorgeous. On the way home from the party this little sweet voice from the back seat says "Ann? I think you should come live at our house." She replied that she had dogs she needed to take care of and so she couldn't live at our house. After giving it some thought, E responded "I think you have lots of friends that would take care of your dogs for you." The kid's got good taste, and he moves fast.
