Being re-written some in the hopes of getting some updates going.
Dear Jethro,
I hope that this letter finds you well.
And while I wish I could have come to you in person like I used too- I'm afraid that doing so is no longer an option since by the time this letter reaches you... I'll be dead. There's so much I want to say and just a short time to say it in, but Jethro, I'm sick.
I have been for a very long time now, with a rare genetic disorder. One that affects the mind as well as the body.
There is no known cure. Only a long time to spend in agony until my body finally gives up on me. And hopefully by the time that happens everything will have been arranged so that the 'package' that I've sent to you has finally reached you.
And don't worry- it isn't a dog or cat. I know how you can't really stand them much.
But you still might end up with one or two anyways. (Just a fair warning.)
No, what I'm sending to you is something more of a personal nature to the us both. Though you don't know it yet. All I can say is, I'm sorry. Really, really sorry. For being so stupid as to keep her from you for the past twelve years. For cheating you both. But I want you to understand that I didn't do it to be senselessly cruel.
I did it because I was afraid that if you knew about her. And she eventually got sick like me and died- it would destroy you. Like Kelly almost did.
After all, what parent wants to watch their child die again?
