I joined Facebook to keep up with my teenager, but really never paid too much attention to "socially networking" on it until I learned to play Uno, Farm Town and Farm Ville. (BTW - I need more neighbors so I can hire plowers :))
When my mother was pregnant with me, she agreed to be followed by a student from Case Western University in Cleveland, OH. That young doctor ended up delivering me. I believe I was her first delivery and my mother kept in touch with her and she with my mother after my birth. In fact, she gave me a little stuffed animal that I still have. When I was 10 years old, my family moved from Ohio and while I had several phone calls with that doctor, we eventually lost touch with each other.
I celebrated my 44th birthday last week and this morning when I got on Facebook to check my farms (LOL), I saw a friend request from the doctor that delivered me. What a trip!
