I almost don't want to admit this, but I can't not admit it. It's a sad, sad, sad day when your child's second grade homework throws you for a loop. One of her "challenge words" was one I didn't know. Nope. Never heard of it. Jeff joked that I could fill a library with all the things I don't know........which is kind of funny. But kind of not. Especially in the wake of this. I mean, a second grade word? I'm totally dejected.
