My husband works from home. Most of his waking hours are spent working, so we don't get to talk much between his work and our parenting.
When the weather is right and my back etc. is feeling up to it I like to take us for a walk around the block. It's a very long, curvy block so it takes about 20 minutes to come back home. We don't usually see neighbors but it's nice to wave and say hello when we do.
Homeschooling means I don't drive my children to school and back every day. That isn't always so bad because looking back to when my older two were in school last school year, I didn't usually talk to the other parents. (Before that school year started I was hoping to make more friends among the parents, or at least say hello in the parking lot, but it didn't really happen. Most parents sat in their cars.)
I call Mom almost every night - that's how we both want it. She doesn't always answer because of her working hours or because she came home too tired to stay up until my children are in bed and I can call, but when she does answer it's great to talk to her. (We live several states apart.) Grandma likes it when I call too, which reminds me - I need to email her to set up the next time for her to talk to her great grandchildren and I.
Lastly, though you probably meant in real life only, I interact with mothers like you on Mothering and elsewhere, and I email a friend or two. That helps!
Teresa, after a day of listening to my two redheads talk at me (the two with Papa's hair color don't talk quite that much) and sometimes a friend, I savor the quiet when they're in bed, too! I feel that I really need quiet to read, journal, and just sit and think, pray, and relax.
