My ex had a lot of faults (of course so do I) one of them was that he drank too much. On holiday he would steadily drink throughout the day and excuse it because he was pacing himself. Oftentimes I couldn't have a conversation with him because of slurring.
Paul is a guy we both knew who drank far, far, too much and his wife found bottles and glasses hidden all over the house in the weirdest of places and he was invariably rat-arsed each time we went to his house. He was also a gambler and a gaslighter and an armchair philosopher. And lazy.
If ever I tried to talk to my ex about drinking too much he would feign innocence and then say that at least he was nowhere near as bad as Paul. And I was a nagger.
It was not only irrelevant to my life what Paul did, my ex seemed to think it was a badge of honour that he was only a small fragment of a piss artist and not at all like Paul.
