I once spent about nine months creating a largish program, and then moved on to another job. I spent about a day educating the fellow who would be carrying on the maintenance. I barely knew him.

About a year later, we met again. I still didn't know him, but he sure felt that he knew me. I remember he greeted me with, "I love your sense of humor", and "If you really want to know someone, you should work on their code for a year." No doubt he knew me as a programmer much better than I know myself.

Talk to someone who's maintained your code. :)
