When Bart came home from kindergarden Lisa is sitting in the livingroom and are playing with the teddybear. When she sees Bart going into the room she gets a big smile on her face and begins to stand up ! Bart sees this and understands what she is trying to do. He walks up to her and are sitting a half meter away from her so she can walk a little by herself Lisa is saying his name "Barty" while she is walking. (: Bart is here nearly 3 and Lisa 1 + 1 month ^^
