Until you brought that up I hadn't even thought of it. I had spent to many years with my son and his teachers then when they told me when he was in the 8th grade that I needed to give him some space
I then stuck to field trips.
It never entered my mind that I could still do it even if all my kids are in high school. We have a school 2 blocks away I can walk there and get my excercize and enjoy the kids all at the same time.
