Karen: Thanks for the excellent ideas. I know it sounds weird, but one of my favorite times of the week is when I take my daughter to gymnastics -- not because I watch her like a hawk, but because I bring a magazine to read. I catch her eye from time to time, watch her if she's doing something particularly interesting or challenging, etc., but most of the time I'm reading.
I don't have much free time, so the idea of joining a book club, while tempting, is currently unpractical. Daddy/kid time - I do that enough, enjoy it, and yes, it is self-nurturing to nurture others.
I enjoy bike riding, but don't get to go as often as I'd like. Perhaps I'll make more time for that before the cold weather hits. Social outlets - I've been thinking about joining the Band Parents Association, which supports the Marching Band that my two boys are in. Perhaps I'll look into that.
