It hits me in waves...
My latest experience was probably at graduation this spring. They were showing the seniors slideshow and this one picture flashed up of a couple of my students when they were in 8th grade. I remembered them looking that gangly and young, but now they look like young adults.
I've gotten over the clothes thing. It's just a necessary evil with being a teacher. I don't go out to clubs, mainly because I don't want to run into my students. Call me crazy
Everytime I think I am getting better with adjusting for my age (I'm 24), something will remind me that I'm not a kid anymore.
