I think one of my biggest worries of raising my children (these days) is that they won't be kind.
I see cruelness in kids. Even at VBS, one of the best of circumstances, kids are mean to each other. Especially as they get on towards 4th grade. I see the beginnings of it in Liam's preschool class, sometimes even in my own son. It's one of the reasons I toss around the idea of homeschooling.
I'm not saying it wasn't this way when I was growing up. It might be normal...but that doesn't make it right.
