I tend to leave early and go to bed, to avoid drunken ranting and rubbish.
I do 'call' people on it though if they upset me and can't remember....the same people who used to take GREAT delight in doing it to me..
If someone drunk texts me, I ignore it at the time, but the next day they will get a knowing stare from me that states I am not happy about it.
If someone drunk dials me, I answer, state that I don't like talking to intoxicated people and end the conversation. If they continue dialing I turn my phone off.
A lot of my experiences with other drunks is in the workplace - my colleagues!!! And I don't work in that type of industry either.
I have very mixed feelings about it. Anger as some behaviours are down right rude and disrepectful towrds women/men. Pity - as I think there are some who don't realise how bad their drinking is.
Empathy - been there and done it myself.
