My 2 DD (7 & 12) totally embarrased the rest of our family by waving the the people passing by on the monorail while we ate at the Concourse Steakhouse! We would count how many people would wave back. Then over at San Angel's we had a table right up front and we would wave to the people passing by on the boat ride but this time we would wave only if they waved first. Cheap thrills. Please tell me if anyone else is nutty like me.
