The man had quickly ENCODED the fact that his blind date was a psycho path since she didn't know how to sit in a chair. And so the second he had the chance, he ran for it.
After he had escaped the "weirdo" he quickly FOCUSED on getting as much alcohol into his system as humanly possible, so that he could forget all about this terrible evening by forcing the event into his short-term memory.
However things quickly escalated when he awoke outside a church. He had apparently blacked out and married the crazy date in the middle of the night which is something he will never forget.
