Routine for driving with kids: Check for appropriate clothing. Check for shoes. Check for all necessary books, papers, money, lunch, snacks. Check that seatbelts have been fastened. Check that everyone has used the bathroom. Check for seatbelts again. Go.
Routine for driving without kids: Seatbelt. Purse. Go.
You can see why it's so hard to go anywhere when the kids aren't with me.
