I remember the waitress thing. We said "I'm behind". It's been 30 years and I still say it in the kitchen. Ever been in a marching band? I still can't go into a mall and not be on my left foot on the beat of the music! And the dance thing...my dance team girls can be identified by the arm movements they make unconsciously as they walk, down the halls, turning in papers. In routines as you move from formation to formation, there has to be an arm movement as you walk. People laugh and say I have them brainwashed, but it's just habit. Now I only teach younger girls, but the parents are always telling me how they have the arm movement thing going on in the stores and around the house. But then, I too, sometimes find myself doing the same movements...

The on your left thing is only a matter of time. Especially as I age.
