Boo has always been able to pay attention for long periods of time. I have a picture of him before he was walking, sliding our closet doors back and forth. Back and forth. Back and forth. Which led into a fascination with elevators. Garage doors concurrently interested him. Ironically, we are the only house in our neighborhood that has a carport. He has found that the Mother of All Garage Doors can be found at fire stations.
He earned $50.00 by doing chores to buy the Lego Fire House set. He's not so much interested in the fire engines but the garage doors.
