How did I get all my Dad's posts?

The weirdest thing just happened. I was working with picasa2, sorting through thousands of photos and I decided to see what this blogger is... I couldn't remember if I had created one before or not so I logged in with my typical login id and pwd. What do you know, I have one. Now, the weirdness sets in... my father died in 2003. All of his old posts are in my blog? How the heck did this happen? As I read through them, my chest hurts.
