The best man is the groom’s brother. In his speech he describes how hard it was for him to do so because even though they lived together, they drifted apart and he didn’t know his brother as well as others.
During his whole speech, after almost every sentence he makes, the crowd erupts in laughter, you can tell he was uncomfortable, it made him feel like he was doing something wrong.
He was trying to reconnect with his brother and offer his support and yet was laughed at the whole time. Do you think the groom chose him as a joke because he was made to?
