to write or not to write???

that is the question. In my last blog I wrote about looking for friends little did I know that Troy Dunn would comment on my blog. I took his advise and have located Kate thru here father's name they still live at the same address. I'm pretty sure I have found Kate's address and now the question is do i write her a letter letting her know I have been looking for her or not??? I'm scared bc what if she doesn't want to hear from me? what if she forgot about me? Or maybe she has been thinking about me and looking for me. Yesterday I looked for my old letters (I save everything lol)I had some good laughs and fond memories looking at them. I don't know what I should do half of me says yes do it the other half says no she prob forgot about me and has moved on in her life come on it has been 8 years or so. But I know if I do write and I don't hear back than yes she has moved on in her life so I guess Ill type up the letter address it and than go from there little steps I guess. I just hope she is still touch with Mary she is the next one I need to find, any opinions will be greatly appreciated :o)
