Please bring me a half-bottle (or two)

We used to buy the little bottles for mil. You are limited on choice and they are more expensive pro rata to a larger bottle. Maybe your friends feel it would be unkind and mean to bring one small bottle. Why not drop a massive Hint that you prefer small bottles?

I’d open it there and then or ask them to take it back as you won’t use it. But then I’m blunt quite often.

When we see friends we take a bottle and it’s drunk that evening, with them.

Why don’t you drink it with the friends who have brought it?

Most supermarkets sell small 25cl or 18.7cl bottles of wine.

Maybe you need bigger wine glasses? If someone brings me a bottle, we'll have a glass each - and there's only half left - so it's not a problem!

If it’s a screw top, just put the lid back on, or cork, something like a Vacu Vin wine saver will do the job, keeps forever.
