I work at my church library twice a month, for 4 1/2 hours each time. it is rare that anyone comes in to check out a book, but I get to have some quiet reading time away from my house!
I have joined the Guadalupana Society, which provides food and sets up and cleans up for parish funerals. I've done one so far. It's great working with all those ladies in the kitchen.
I helped out at my kindergartener's school a couple of times this year, but then women's Bible fellowship started.
I will be drving a woman from our church to her kidney dialysis one friday a month (she goes 3 times a week and there's a group of people who take turns). Her treatment is an hour from here and it takes hours. I will incorporate my monthly trip to Walmart and do some other errands in that town.
I spent many years as a crisis pregnancy counselor in the mid 80's to mid 90's.
