Facebook surprise

I logged on to my facebook account this morning and saw a very surprising friend request that I have not yet accepted, and have been thinking about all day. This has had me questioning forgiveness and what the lack of forgiveness could say about me as a person.
I am the product of the stereotypical deadbeat father. One of earliest memories is waiting on the porch for my dad to pick up my sister and me. Well that pick up never happened and he was never seen or heard from again. My mom did try to track him down thru the court system once, but he quit his job and disappeared again. These are the type of men who have made life so difficult for all the real men out there who look at their children as there sun, that they revolve around, and would be destroyed without.
Later my mom did meet, and marry a single father who took my sister and me into his life as if we were his own. The world is full of these fathers, but you won’t see or hear about them on the news, and regardless of politics, you have to respect vice president Biden for being a father that was there to raise his two sons after the tragic loss of his wife and daughter.
I try to be a good person, to take responsibility for my actions, give everyone a chance, and be a forgiving person. These values have been in question to me today since I saw a facebook request from my biological father this morning. This man left over thirty years ago, was not there for any part of my life. I think the only part of character building he had on my life was that I swore thru out my life that I would never do to my children what he did to his. I don’t feel anger toward this man; I really don’t feel anything about him. He is just a stranger out on the street. Perhaps I am a little angry; I’m trying to weigh the pros and cons of contacting him. This has been a lot tougher decision then I would have ever thought. Well I have some soul searching to do on this subject. I will keep you posted.
