He could do this all day long

If you were a fly on the wall in our house at any given moment in the day, I'll bet this is what Mr. Boy would be doing... ever-so gently playing with his cars (only one at the time and only with one finger) while leaning up against the coffee table. He literally goes around the table with his cars all day long. Only trouble is having to follow him around and around, untangling the pump from the table legs! :) He's got a pretty calm and gentle way about him.
