Because I'm awesome!
Oh heavens, my son got chopsticks at lunch today. He came into the living room, grabs something out of the drawer, and starts to leave. I say "um Ozzy hand me the pencil sharpener" He says "how'd you know I had a pencil sharpener?" I said, "because you are Isaiah, and it's not chop sticks its some sort of ninja weapon and I know you'd try and sharpen them!" Mom skills!
