My FI has six people he wants to invite to be GM's: Two old Army buddies, two friends from high school he still talks to regularly, his brother, and his BIL. My mom has been helping me plan the wedding, and she seems to think six is way too many people. But these are the people FI wants to stand up with us, and frankly I couldn't care less if it was one person or twenty. If that's who he wants, then I think that's awesome.
For me, though, the decision of who to pick has been harder. I knew I for sure wanted my sister, and FI's two sisters who I'm pretty close to. But I wanted friends up there as well and hadn't been able to decide who. Finally, I thought to myself, "Who are the friends that I turn to when I'm happy or sad?" And four girls came to mind, all classmates from grad school. So assuming everyone says yes, that's six GM's and seven BM's.
Honestly, rational me says, "What does it matter? All they need to do is wear a nice suit/dress, hold some flowers if they're a girl, stand next to you during the ceremony, and pose for some pictures." These are the people I and FI feel emotionally closest to, besides each other. But the irrational part of me is listening to my well-meaning mother wail about my "million people" wedding party.
So please, if I'm nuts and this is too many people, tell me. If I'm not, please tell me that too. I need thoughts from people who have been there and who are not related to me.
