"Want one? The bottle is over there and a glass is there waiting for you. I think you'll want one. I know I did."
"So, you probably have questions, so let's get the obvious ones out of the way first. This is your wife's body. My head is attached to your wife's body, a medical procedure, my head was grafted on, and her head was grafted onto my body."
"Also, to answer the likely next question, no, this was not my idea, it was hers. Seems like she wanted something different, and well, so did I. Don't worry about her, my body is in very good shape. I know my face doesn't really give that impression, but I am, well, was."
"Now, for the any more information on her reasoning, you'd have to ask her. Assumedly she still has her phone. She spoke well of you. You didn't do a thing wrong. What's the phrase, "it's not you, it's me"? I thin that's it."
"Anyway, as for why I'm here, I agreed to relay this message to you. She let me in, got me set up a bit. If you don't believe me, call or text her. I'll just wait here, enjoying the wine. Speaking of which, you may want a glass yourself. I can't even imagine what it's like to hear all this but even me speaking this made me want to fill up my own! So, why don't you have one, call your wife, and I just wait for you."
