I'm not quite sure that this is the appropriate board for my question, but here goes anyway:
FI is an only child and I have a college-aged brother whom I love dearly and really want to involve/include in the wedding. But we decided early on that FI doesn't feel close enough to my brother to make him a groomsmen, and I felt (and confirmed with my brother) that he'd be uncomfortable being my guy of honor, or a bridesman, or whatever. He is also pretty strongly anti-religion, so I don't think he'd be comfortable doing a reading. Is there anything else he could do in the wedding, in addition to or instead of being an usher, to make a point of the fact that he's my only sibling and is special to me? He is going to be my witness on the marriage certificate, but that's not exactly a very visible position.
