It just goes to show that you're never too old to learn new tricks!  I have kept out of the social networking arena for so long for the simple reason that it baffled me.  However, recently a college friend told me that many of our old pals were on Facebook.  So I decided to jump into the fire and give it a try.
 
I just joined yesterday and I've already reconnected with so many friends from high school, college, and elsewhere.  I've thought about many of my old friends often over the years, not knowing how to get in touch with them.  Facebook is great because it gives an informal opportunity to "catch up" with people, say "hi", and see what they're up to.  I also like that people cannot see your profile unless you allow them to be your "friend." 
 
So give it a try if you haven't already.  It's a lot of fun, even for un-"hip" people like me!
