Minus a "Friend"

The other day I realized that a coworker removed me as a friend on myspace and blocked me on facebook. I am quite confused as to what may have caused one's recent actions. In pondering, I know that I have not put anything inappropriate on their pages nor do I have anything on either of my pages that would cause one not to want to be associated with me. This leaves me with the perception that the drastic removal must be work related. So, my conclusion is that I have pissed off a coworker due to business related tasks and as a result I have been removed as a "friend" on these social networking sites. Too funny and quite childish!
