When do you feel most adult?

This evening, I opened a package. Something I had been waiting for. A new toy, I guess. And I thought, I can't wait to experiment with it this weekend. A very slow sensation took place. A creeping realization, as I thought back to a conversation and connected that memory to this very moment. THIS is considered a hobby and something I could say I'm interested in. I felt very adult in those few minutes, as I sensed myself gravitating further away from my former self, as I continue to find different and respectable "grown up" things to do in my alone time.
