I never knew this topic existed.
I have an old friend, I don't see her much any more for various practical (rather than emotional) reasons but we are fond of each other. She has one child and is pregnant. I know she has drunk, and been drunk, several times during her pregnancy, and before her pregnancy drank quite a lot - a bottle of wine before & during dinner, and one after. That's a lot.
It's always been in a gay abandon kind of way, (and in the past quite often I have been out having fun with her) not drinking under the bed or anything. But I can see in her eye she has a kind of cold thirst for it ifswim, gets argumentative if you say let's not have any more, doesn't remember things the next day. When we were 20-odd it was how we had fun a lot of the time but surely we are too old for this now (late30s)
Do you think it's appropriate to say anything?
