I figure it this way: I dabbled in growing my own food and making my home less dependent on gas and electricity and so on, but I didn't go far enough, and I didn't succeed in bringing my family along with me. Our kids seem to want fairly conventional careers - although Ruth is fascinated with "tiny homes" and may study architectural technology - so it doesn't matter how many vegetables I can grow in the back yard, when they will be needing money for tuition and accommodations. The marriage breakdown adds another layer of formal obligation, too, since the legal people will be looking at whatever agreements we come up with to see whether the children are provided for adequately (and I am sure they will be looking at dollar signs, not bushels of food). This teaching program is the fastest way I can see to get back onto a fairly lucrative career track while still making use of my science background, being able to work in my home area, and being able to cultivate a little more ecological awareness. I know, walk the walk. Well, at least I will have late afternoons and July and August for gardening.
