Why follow people on FB

I been on Facebook over a year now and I have connected with alot of old friends. i can not say IO have met anyone . But I have met people and then ook them up on GFB and become there:friend" Nopw I know what they do in there life and they mine and maybe some of my family and friends lives too. Is that a proble for anybody else. I wonder how long befor someone says something hurtful or worse. Oh well I am a self help freak so I am going to use this blog to get er done as fellow hoosiers say ....!
