I would be feeling the same way.
The whole social network thing is not in my cup of tea. My AW has a FB account and I sometimes wonder if her best friend ever makes comments about me. Her best friend is an alkie to. In the end, I'm happy I don't have a FB account. Too much drivel and nonsense. I've got enough stuff to filter in my mind.
This isn't a dig on you or your involvement in FB. Do what you do and keep sitting on those hands.
