Playground Illusions (and Allusions)

Alex and Ian were playing "pirate-ship" on the jungle gym with a bunch of kids the other day, and Alex started yelling, "sirens, sirens, watch out for the sirens!" and I thought he was talking about some sort of imaginary approaching police boat, but then he continued, "don't listen to the Sirens' singing! we're going to crash into the rocks!" and I realized that-- for better or worse-- that I am raising a nerd.
