How does the best man get married?

I went to the bride's house with the groom in the morning. The best man took a red envelope and candy. When I arrived at the bride's house, I gave a red envelope. The bridesmaid should give you more, and it won't be too hard for you. When the bride goes out, she will open the door. If a car stops on the road, she will sprinkle some wedding candy. When she arrives at the hotel, she will have to open the door and get off. The host will tell you the following.
