I saw that one kid was dressed as a ninja. Good costume, too; committed. PAY OFF THAT COMMITMENT, I must've been thinking...
...because when I was walking a few minutes later, the kid was coming back and headed towards me. And I cried "Ninja!" and leapt for my life to my right.
And took a header into a chair I didn't expect to be in that aisle.
"I'm OK!" I said, turning over and raising my hand. Worst damage was (is) a cut on the bridge of my nose -- my glasses stayed intact! -- and I hope that's all. Like, please don't have that kid be scarred for life by watching me hurl myself. Please let him just be amused instead.
And I know people who know how to do stage combat, so they KNOW how to fall. Pick their brains, why don't I?!
