I wash my hands (rerun)

I do, but not every one of my fellow student does the same. I was at the library studying and I went to use the restroom, there was another guy in there that I recognized as one of the second year med students. When I finished, I washed my hands. He did not, he didn't even flush the toilet, he left without washing his hands. That bothered me. Here is why.I wash my hands everytime I use the facilities. I never used to do it that often, but ever since I began my journey to become a physican I make sure to wash my hands everytime I use the bathroom, especially in public restrooms. Why? Is it because I know something now that I didn't now before, no. I knew before that I should always wash my hands, just like I know it now, its just that now, I am in training to become a professional, one that is held to a certain higher standard and needs to be a role model to his fellow citizen for many things, one of which is HYGIENE. How can I tell others to obey the laws of hygiene, at least while in public, if I don't do it myself. Am I wrong? Am I wrong for thinking the guy will make a worthless doctor? I could be wrong, its just that I feel so damn right.
