It wasn't just one night of drinking sadie.
IT WAS NIGHT AFTER NIGHT.
It wasn't a night of drinking Stephen, you are grossly exagerating. They were eating their meal and having SOME wine with it, as most people do if the opportunity is there.
As you say, they ATE a meal every night and accompanied it with a glass or two of wine night after night.
As MOST people do
I would bet that 90% of people would have a glass, or so, of wine if it came free with the meal, as this did.
It is you, Stephen who is out of line with the reality of what most people would do.
Having a glass or two of wine does not equate to being drunk, especially when taken with a meal. There were no reports of drunkeness or being tiddly ....and to be frank, if say, the hubbie got a little merry and the wife stayed sober, there was no real problem anyway.
BUT there is NO report of anyone getting sloshed. Not a single report, so why keep going over something that never happened?
