Sidney and Lucas' conversation in the back seat...

This week Sidney and Lucas were having a conversation in the back seat of our car that I overheard, it went something like this...

Sidney: "I thought that kids at Christian school would be a lot nicer than people at a public school."

Lucas: "Yeah, me too. Why do kids that call them selves Christian don't act Christian?!?"

Sidney: "I don't know, it's just really weird."

I wonder what that's all about? :(
