Unfortunately, this generation of children, and especially those we identify as "tweens," is at risk of developing a cynicism so entrenched they will doubtless become jaded. After jaded, there is apathy, and after apathy, an immature conscience that dismisses "good" and "bad" as simply definitions of relative self-interest.
Make no mistake; I liked my daughter's metaphor about seaweed and celebrities. In fact, the cynic in me wonders if she got it from one of those witty sitcoms she watches on Disney.
But just to show good faith, I'm not going to ask her if she heard that expression on TV, but instead I'll give her the benefit of the doubt and applaud her pithy turn of a phrase.
While I'm at it, I think I'll have a talk with her about healthy cynicism, with emphasis on the word "healthy."
