Do I call?

My Dad's old friend called me this morning. I had called him to see if he knew where my dad was. He was the only one that I knew that MAYBE knew something about my dad. He was not sure about anything but promised me that he was here to help and then quickly told me that he would make some phone calls and then get back to me. OK, let me just admit that I never in a million years thought that he was going to call me back. I just did not have a good feeling about it, SOOOOOOOooooooo when the phone rang a week later and it was him let's just say that I was shocked! Anyway, he told me that he had gotten up with my dad's twin brother (he has a brother?? and it is his TWIN brother! What?! OK, quickly regroup!) He and his wife live in Charlotte and they know just how to get up with your dad! WHAT?!? I was visibly shaken and had to sit down. You mean, they know where he is and are expecting my call today? They can't wait to talk to me and tell me how to get up with my dad? I could not get off the phone fast enough. I said my thank yous quickly so as to get off the phone as soon as possible. Randy graciously complied and then there I was with a phone number that would lead to info on my dad. I am not sure that I am ready for this. I mean, am I really prepared? OK Wini, enough excuses, just call already. I am dying here. I made the call and the person on the other line related to me by blood proceeded to tell me about my dad and where he was living and that he wanted me to call him. Oh, and here is his number .........again, I quickly went through the thank yous as I had done before, only with a little more feeling. I had to get off this phone so that I could stare at this number. Finally, goodbyes were said and then there I was... left alone, with his number....Oh Lord, help me...what should I do?
