I really relish the time I spend every day, waiting for the end of school sitting in my car. No, I don't carpool; I like talking alone with the L-0ne on the way home; sometimes interesting facets of the day arise. Sometimes just the radio is playing, or a CD is on.
While I'm waiting, I can read, knit, listen to a book on tape, put my head back—rest my eyes, as my grandmother would say.
Of course, I look out for a shady spot. It's quiet when I arrive; no girls about yet, except those involved in varsity sports, getting ready to run, or get on the bus for an away game of some sort.
When you work at home, with your spouse in the same working space, a bit of privacy is indeed called for. A great need to get away from all of it, all contained in your car—on the way there, sitting there, dappled (it is hoped) in shade. Just waiting.
