Re: 2 cars to kids' events. We have 2 kids often headed in opposite /conflicting directions on the weekends to participate in their events while we also try to get all the errands done. We usually all go in separate directions or all go together, but on occasion, DH and I end up meeting at same place in separate cars. The only other alternative would require violating some laws of physics.
I would not have anyone adopt my mode of living...but I would have each one be very careful to find out and pursue his own way, and not his father's or his mother's or his neighbor's instead. Thoreau, Walden
