While this is not an issue for me, I will chime in.
My youngest goes to a private school where many of the moms do not work. Said moms hang out together during the day and drink away. This is not just the occasional drink, I mean hang out at the winery on a regular basis while the kiddos are in school. Then go home and drink some more, or to the club in the evening for dinner and coctails.
For some it's not become a problem. For a few of them, you can see the alcoholism progressing. Truly, this addiction knows no boundaries, and knows no social classes.
