Sir, you have created 4 major language, syntax and English literature flaws in your incredible tale. Simply put, this charade did not happen, as your vivid imagination suggests and, most probably, not at all.
Your flaws, nothing to do with the implied scapegoat of forethought, "from a sometimes faulty memory", are easily spotted, by anyone with a smidgen of common sense, in the Me and Andy quotes, 1 blatant in yours and 1 in each of the 3 short sentences you attribute to Andy.
A valiant attempt at deception, at best, just can't figure out your motives. When you write fiction, it must flow well and make sense to the reader. When you quote portions of a conversation, particularly a recent one only hours old, in which you were a participant, it would easily be reproduced exactly as it was said. Your story does not do that and therefor is a fictional novel, sort of. Why don't you search through that sometimes faulty memory of yours, find the 4 flaws, correct them and quickly edit your draft so that it is less unencumbered by the truth and post your fiction again for us. But, Good For You (GFY) for trying.
