My FI is in the process of narrowing down his guest list.
He's inviting his Aunt, who has three grown sons. The youngest son currently lives with FI's Aunt, but the older two have families of their own.
My FI grew up with the middle son, and wants him to be a GM. He's never been particularly close with the other two sons, and is on the fence about inviting them.
Thanks to this board, I've become better versed with wedding etiquette, but I can't remember what etiquette says in this case.
Is it appropriate for FI to invite his Aunt and only one of her sons (whom he wants to be a GM), or should everyone be invited?
