Too old????

Do you ever think you are just too old or too crabby to do your job?? That is kind of how I feel today. For too long, I think I've wasted my energies on things I care about but to be honest no one else does....Does anybody care if I hang sparkly curtains on the back of the stage? Or stand up on a ladder and hang twinkly lights on the short curtain?? Or twirl lights around a hugh pillar?? I mean, does anybody care??????????????????????????????????????? I try to incorporate all sorts of kids and still somebody crabs. I do so much right and then I blow it with one rude comment. I just don't feel like bothering anymore. I just don't.
