Everyone's second question is "Are your parents mathematicians?" My mother is a retired waitress, and my father is a retired bartender, so the answer is no. Or at least, in the strictest sense, is no. They have no formal training in mathematics beyond the standard U.S. high school education. However, they have been known to do simple addition, subtraction, and even the occasional multiplication and division in their heads, so maybe, given today's standards, they are. I'll let you be the judge.
Once in a while, I am asked if I like being named Pythagoras. After all, didn't I get kidded a lot when I was younger. The answer is "Yes" to both of those. If fact, there are those who will kid me even now. If I had a nickel for every time that someone called me "Apple Py"... Well, you know. I find that the positives far outweigh any possible negatives. Many a conversation has been started by someone asking about my name. Plus, I have yet to have a name collision. I tend to be the only live Pythagoras in any group.
After basking in the full glory that is my full name, most people like to call me by something a little shorter. By far the most common (and conveniently the shortest) is Py, pronounced like pie. Nevertheless, there are those who insist on nonconformity, so Pyth, Pythag, and the ever confusing Cat have been used at various times. While it perplexes some, I don't invest much of my identity in my name, so any of these is fine with me, as well as other choices one might come up with.
