Spying on My Daughter on Facebook.

I read in the news how Facebook is giving out all kinds of private information and that you better watch out or people/companies/schools are going to pick up things about you that you don't want them to know.  Well, my daughter could work for the CIA.  Every once in a while I check her Facebook page. It's really not stalking...it's just...well I guess you could call it spying.  I just take peek, I don't leave a message and I try and cover my tracks.  This is how I find out some very revealing details like:  "Productive day"..."working doubles"..."need a vacation". She has no idea I'm doing this unless she reads my blog which as you can tell by her Facebook entries, she's much too busy to do.
