Your friend is anal-retentive. I had a friend like that - actually learned to drive stick shift with him in college (in his saturn) I got the hang of first really quick and went to shift to second and he got loud. "No! Today is only for first gear! We'll work on reverse tomorrow! No second gear!" or something to that effect.
It was a hoot watching him try to pump his own gas for the first time (he was from NJ). Had the manual open and everything - read all the instructions on the pump. I tried to help him, but he waved me off. Had to do it by the book.
