I resisted for a long time but finally gave in to peer pressure. I really hate talking on the phone so Facebook actually makes it a lot easier for me to communicate with my family. My "friends" are all people who are related to me. It's a nice way to keep in touch without me having to pick up a telephone.
DD is at her dad's for part of the summer and then off to college. I've noticed that she and I spend a lot of time chatting and sending each other messages through Facebook. She used to send texts all the time and I'm unbearably slow at that so I prefer talking to her this way.
