My world revolves around family. We live in the same home with our daughter's family which includes a college attending son and a daughter in high school, 2 dogs and 2 cats. My wife and I lack little in daily contact and have another daughter who pops in a few times a week (or we pop in there). Her kids live nearby, along with one of our greatgrands.
Our social life, by choice, is pretty much limited to these folks on a daily basis. Haven't visited one of the local senior centers for 5 years or so. I enjoy a couple of forums but don't post often. It's like picking up the newspaper, or book, and seeing what's going on today or where the story is going.
I find most of the folks on these forums to be interesting and friendly, with a few political hardasses (mostly hidden by forum rules) but these unpleasant folks are found everywhere. I can enjoy the camaraderie on these forums but don't need it on a daily basis. Family fill any void that we have regarding company.
