Speaking of waving at things.... I remember taking a friend to Halifax back when I was 17 or so. He had never left his small town before so Halifax, although not huge, was a city of wonders for him. Me and another buddy had some fun with the motion sensing doors going across a raised pedway. We made a point of waving our arms in front of it in a big, overdone gesture to see if he would follow suite. We started letting him go first and sure enough, he waved his arms like madman in front of very big glass door we came across.
