The best memory I have of alcohol doing strange things to people was when my ship was pulled into Sandog, and one of my buddies had just received a Dear John letter. He wrote out a big letter back calling his ex all kinds of nasty things, put it in the mail box, then went out on the town to get rip-roaring drunk.
He came back later that night completely gone, and decides that he really doesn’t want to say all of those things to his ex, so he tries to break into the post office and retrieve the letter.
Shore Patrol picked him up trying to scale a barbed wire fence at 2am, returned him to the ship, where he then spent the next 45 days on restriction and lost a chevron.
The kicker? It turns out he had put the letter in the ships mailbox, and it had yet to actually get transferred to the base’s postal system, so even if he had managed to get into the post office on base, he would never have found the letter.
