Conditions for being the best man:
First, we should have a sense of responsibility
At the wedding, it is difficult for the bride and groom to take care of both things. Just as the bride has her own best friend think tank, the groom should also have a group of brothers and groomsmen who can come forward to solve their problems at any time. So the minimum standard for choosing the best man is not to cause trouble to the groom. Although it can't help, at least it won't cause trouble to the groom. If the groom insists on inviting the buddy to be the best man knowing that he is drunk, he will have to ask for it. Of course, the best man who doesn't make trouble is still a little short. It is best to choose those who are responsible, can do anything for their brothers, and can stay awake and rational at critical moments. In this way, when something happens at the wedding and the groom can't get away, you can rest assured that the best man will handle it.
