We went to a birthday party today at a place called "Pump It Up". It's an indoor play arena filled with inflatable "moon-bounce" structures. Sean barely met the height requirement, and lucky for us he did. I think he may have mounted another protest if we had not allowed him to join in the fun. He spent an hour running and bouncing around, saying "Whee!" every 5 seconds for the entire time. Even though the bigger kids occasionally knocked him down, and he got beaned with a ball or two (one right in the face), none of this fazed him in the slightest. He was sweaty and exhausted by the end of the party, and gave hugs all around.
