Scott and Mason dropped by last night on the four-wheeler. Mason has a helmet with Elmo and Sesame Street characters which he was very proud of. Scott chased Mason across the backyard, catching him, "tackling" him down to the ground, and tickling him. They probably did that for 20-30 minutes!
When Mason and I were walking up the stairs from the basement, he pointed to the carpeting on the front of each step (not on the step) and said, "We have this at our house. It's called a "thinga ma bob." We have lots of "thinga ma bobs" at our house.
Then they were off again back home (about a mile).
