This topic called me - I'm 33 years old, and for Christmas last year my mother bought the original TMNT movie. They were also my first "real" concert. *sigh* Michaelangelo was the coolest - I sculpted him in clay one year for art class. My mother still has it. *giggle*
Anyway, I totally feel you. I'm really struggling off and on as it's just so hard for me to give up some things that were just staples of my life, and were used as rewards. "Hey, you read so many books that you're going to get FREE PIZZA from Pizza Hut!" It tastes wonderful but I feel this mortifying guilt afterwards as when I eat it, I EAT it. None of this girly nibbling on one slice and proclaiming fullness. Oh no, I'll eat half a pizza and only stop because my friends will be eyeing me warily.
There wasn't really any point to this posting other than to agree with the fantasticness of TMNT, and to commiserate over pizza. :-)
