I'm getting old

So as I was trying to be a cool coach at dance practice yesterday, I realized I am getting old. When did this realization hit me, you ask? When after doing about 10 toe-touches, for teaching purposes, I did something incredibly bad to my back. For the rest of practice I walked around like an 80 year old, and the girls kept giggling, which I can't blame them, and I knew, I'm just not young enough to do those kinds of things anymore. At least not the way I seem to be doing them. I didn't think that 25 was that old until yesterday. Maybe I just need to go get a physical and discuss things with my doctor on how best to do a toe-touch at 25 and not hurt oneself! Other than that, dance seems to be going well. We have 16 girls for sure, 18 girls maybe. There are a couple who haven't shown up to either of the two practices that we've had, and I don't want to call them and beg them to be on the team, because if they want to they will, if they don't, they won't... right? I have come to realize that I'm not a good coreographer. I can rip things off from a dance here and there, but putting a cohesive routine together is quite a bit harder than I thought! The uniforms we are getting are so cute... but I'm feeling a little big weird about them... I don't know- what do you all think? I'll attach a pic, but the kids are waking up so I need to go- take care!
