Awesome on volunteer work! FEM, I too wonder what I would do if I wasn't wrangling critters, canning, cooking, gardening, baking, or working around in the shop all the time!
Well, it's about putting your talents to work, I guess. Some of the skills needed for growing things applies to growing youth, too. Patience, perseverance, planning ahead, getting a good plan together, reacting to ad-hoc situations with your knowledge and experience, enjoying seeing the fruits of your labor. You be surprised at the parallels.
I don't think any of you I know here would sit around and do nothing.
You're right. I wouldn't even last a week. One year I had to take my DD to summer camp, then pick her up and take her to another location for a week. It was cheaper for me to just camp for a week-by myself. I was going nuts!
