Something I love about kids is that they haven't acquired a lot of information yet. This leads them to say things that don't make sense or aren't entirely true. However, they think it's true because it falls in line with the information they do have (known as "schema" in the education world).
Now I'm not saying that I make fun of them when they make mistakes like this. I don't. They can't be expected to know as much as an adult. They're still "works in progress" (hell, we're all "works in progress!"), but when they say something that is nonsensical or just plain wrong, I can't help but be amused.
Today, one of my boys complained that another boy called him something homosexual. (Yes, this is the kind of crap I deal with daily). I called the other boy to me and asked him if this was true. The boy admitted that, yes, he did call him something homosexual. I asked him what he called him. His reply: "masturbator."
Hee-hee...I guess there are a LOT of homosexuals then!
