I think some Ts take it on faith that those things are scientific, though.
I actually have a funny story about this subject. I was at the State Fair and was exiting a spinning-type ride. A little kid behind me was pushing on me and trying to get around me. He shoved around to my left. I stepped left. He shoved around to my right. I stepped right.
"Time this kid learns to wait his turn,." I thought ohsovery parent-like. We weaved and bobbed and it became his will against mine and, damn, that kid was NOT going to get around me.
He finally couldn't hold it any longer and threw up all over my back! Do I move for pushy little kids at fairs now? Damn betcha.
