Family circumstances have me homebound with just a few hours a week to not be home. So SW and FB are two of my viewports to the outside world. Probably average a couple of hours a day here and FB. I'm also usually doing something else when here.
I'm also a music fan, and I once read someone's description of the late Dr, John's piano skill as him being able to play two different songs, one with his right hand, the other with his left, simultaneously. The only two things I can do simultaneously is walk and chew gum, and even then I sometimes trip. So for here and FB, it's more like I'm here and not-here for a few hours a day.
