old and ignorant

I'm starting to feel old, and I'm wondering if I'm going to feel old for the rest of my life.

Things that make me feel old:

- my baby brother going to college next month
- having my knees creak and my wrists crack
- meeting up with an old high school friend who's been married for four years
- going to weddings, in general
- my friends graduating from law school and med school

I used to always feel young and ignorant. Now I feel like I have no excuse for my ignorance.
