We took my 4 yr old son to LegoLand in California. We were waiting in line for a mechanical pony ride that he was very excited for and could do by himself. The attendant was asking every child their age before they got on the ride. We hadn’t thought to talk to him about why. When he got to the front of the line, the attendant asked him his age. He hesitated and looked at us. We reassured him. Then as cool and confident as could be he said “um … 18.” Everyone within ear shot was rolling. Apparently he was worried that he wasn’t old enough.
