Another direct quote, this time from my, ah, Mary's Dad.

Dress up week was a lot of fun in school, though I really didn't participate much. As if I'd really go to school in a blue flower and lace nightie for "Pajama Day". Not that Mom would have let me in the first place. What gets me is who thought having a "Nerd Day" was a good idea. You just get lines like "You don't need a costume because you already are a nerd." >_< grrrr
