Sign I am a grown up:
I spent money, intentionally on buying three surge protectors for my house. Not anything sparkly, not candy, surge protectors. Plus, I didn't even have any surges beforehand to teach me a powerful life lesson.
Sign I am not:
Looking at people's facebook pages I realized that one of my old friends had gotten married. I don't know exactly why this was such a shock to me because umm that's what people do. Then spent the next half hour saying repeatedly "She got married to a boy".
