My brother is 27 and I would love to have him involved in the wedding. My fiance and him get along well but aren't necessarily friends. The rest of the GM will be my fiancé's 3 friends from college and his brother. The entire wedding party will be around 21 years old. He's not the "read a poem" kind of guy either. I guess I'm just wondering if it'd be weird to have my brother as a groomsman because him and my fiance aren't that close and there is an age gap. What do you all think?
