Halloween

Me: Hey, Eli.  Kiah and Anna are going to be fairies for Halloween, what do you want to be?
Eli: A boy fairy!
Me: A boy fairy? (I was a bit shocked because it was such a departure from Spiderman... not to mention I was trying to figure out what it meant to be a boy fairy)
Eli: Gotcha.  I want to be Spiderman (with a tone in his voice like there was no other option)
