Planning a Life

I swear I think my kids need collaboration software to lead their lives. I ask them every week if there is band practice and at what time? "I don't know mom," they say. I generally find out on the day. Like I don't have a life. Once Dan starts driving next year I won't have to worry too much about chauffeur services but still, these kids see each other all day in school and then IM each other all night. They can't get their schedules coordinated?
