My age must be showing. The following quotes are direct from six and seven year old students in my Primary Ballet class yesterday while we were stretching:
Me: Everyone make your butterfly wings and bend forward as far as you can!
Student #1: Miss Sarah, I can go farther than you!
Me: That's great!
Student #2 (to student #1): It's because she's old.
Student #1: Yeah, her bones creak.
There you have it. I am officially old. Too old for butterfly stretch. The end.
