Daniel: "Mom, why doesn't Katie have a curfew and I do?"

2:30pm - ring on the cell phone from Katie: "Im going to Charlie's, I will be back later."
8:30pm - Phone call from Katie: "We're waiting for some people to come over, probably won't be home till around 11"
10:55 pm - Phone call from Katie: "Just letting you know we're leaving Charlie's just now.."

That's why Katie doesn't need a curfew. It's all about communication, boy...
