Beth, age 4, has lately been practicing her evil mad scientist laugh.

Doesn't take anything seriously
Luke: [age 7] "I tried talking to [another 7-year-old boy] about God and stuff."
Me: "Really? At school?"
Luke: "No, on the bus on the way home. I asked him about God and about good and bad. Like, what are you supposed to do with your life? Is God real or just a fairytale?"
Me: "Wow, that's pretty cool. What did he say?"
Luke: "He didn't really say anything. He just laughed about most of it. I think he's the kind of person who doesn't take anything seriously except jokes."
