Baby Bog is always up by 7:30 am, Bigger Bog will wake up by noon, those teens you know. I am an early person, but 4am is not early, it's the middle of the night. Nobody should be expected to perform dangerous skills when they normally are asleep! Driving included!
Great news about the time change! Hurray! The girls will have fun skiing, too, I'm sure. It's too bad about your son, though. What a bummer. I can't even think about the time my kids leave home yet.
