I left home in 1975. After college, I learned that my best friend from the neighborhood had moved to Wisconsin, developed epilepsy, and died. I always regretted that I had not heard in time to talk to him before he died or even to attend his funeral. Imagine my surprise a month ago when I found out he actually was alive and had found my sister on Facebook. I'll admit that is not as good as finding a lost son, but it shows how these social networking sites can do good work as well. I still guard my privacy, but I recognize the utility of the internet as well. Jim in Detroit
