Passing Cars

Troy has determined that he can now climb up onto the couch in my office, heave himself onto the armrest, and look out the window.  He's the perfect height for looking over the window sill, and now he has the confidence to go with it.  So, while I'm working, he'll stand there looking out the window and watch the passing cars.  And every time one goes by, he'll say, "Vroom, vroom!"  Which is his latest noise to represent what a car sounds like.  Credit for that goes to his mother for showing him all those racing videos.
