Drum roll, please...
That's a big, fat NO!
After torturing me with a re-visit of the very-time-worn ladybug costume, and throwing in a previously-never-even-hinted-at "I WANNA BE A KITTY" (which I have absolutely NOTHING from which to manufacture a costume) Anna strolled into the room offering her old dragon costume and saved my life.
NOT that I would drop everything and suddenly produce a kitty suit out of thin air to spare myself the agony of prolonged whining mind you, I was just getting weary of the fervent mind-changing. I didn't care if she wanted to be something else as long as it was reasonably easy and wouldn't make us late... er, any later... to the pre-trick-or-treating party at Auntie Dawn's house.
With this decision *final* we dashed out the door and up the hill for pizza and candy corn flavored (EWWW!) soda. She had a great time collecting candy, as did all the kids, and was, of course a KICKIN' dragon. :)
