If after the second bottle you see that the family members are too distracted, focus on those who are most like-minded. At this stage of the evening it is more than likely that you won't be able to get the more rebellious ones back on track. As the wines go down, we will lose followers, it is a reality, the sooner you assimilate it the better. This will lead us to tie ourselves to the unwary who continue to pay attention to us and literally give them the night.
It is more than likely that all your fears have been fulfilled, and that the wine is flowing but nobody pays attention to it as you expected. In this case, acceptance and assimilation of the new reality is the best advice we can give you. All will be lost, but you will always be able to tell yourself how wonderful the wine you are drinking is.
Although it may seem to you that everything has gone wrong, if your wines have been a success, you will notice a particularly relaxed and pleasant atmosphere, and you will know that an important part of this atmosphere is thanks to your careful selection. Surely by now you have already thought of a less ambitious selection for the next parties. Don't worry, this will be erased from your mind and you will go back to getting involved as usual with wines because you like them. Because Christmas with good wine and, above all, shared, is much better.
