Age age go away

I don't know when I started getting uneasy whenever I was asked my age. Maybe at 26 I started feeling "over the hill" so to speak. Now, I can consider it downright rude when someone asks my age. It's not that people have ever accurately guessed my age, it's just that maybe I'm not where I thought I would be at this age. Which begs the question.."why am I still single?'" Yep I'm putting the question out there. The universe should answer in kind, this is driving me crazy really.
