This is such a hard conversation and topic. I think typically we tell people to pour it out and then go to the doctor, but not everyone has that luxury.
I know what you mean though. The bus I take home from work picks up at a park in downtown where all the old alcoholics congregate. The drink all day type. Honestly? I think the onus falls on the lack of resources and support for addicts.
I dunno. I just wanted to let you know I think about this too.
