Character names

I was reading through some old stories, stories that I wrote 2 and 3 years ago, and a funny (or maybe interesting is a better word) realization hit me: the same character names appear again and again. The characters, themselves, are different, but the name Pete or Peter shows up a lot, as does Lily (Lilly) and Claire. I have no idea why. Maybe these were MY names in a different life. Ha.
