I have a question about the traditional MOH toast. We are having a small wedding party with just our siblings + FI best friend as his best man because he doesn't have any brothers. Because of this, my 3 best friends since I was 5 years old are not going to be BMs. My MOH is my younger sister, who will be 18. She's very shy and doesn't want to make a speech at the wedding. I have been thinking of asking one of my best friends to make the speech instead. She is not going to be a BM, but I feel like this is not a big deal because she probably knows me better than anyone else at the wedding and I would be honored to have her do the speech. What are your thoughts?
