this part is difficult, but if YOU weren't there, and someone else was, they'd be getting the same crap. he needs an audience. why? that's the mystery...alcohol feeds an inflated sense of self importance, of being the Be All to End All. his drinking used to take all of your attention....even if it was negative, he still had an audience.
well done on not engaging. on just observing the insanity of it all. i love the random "going to be a cop" throw away. try to keep anything he say while under the influence with that same attitude.....just bloviating.
