We think this graphic is perfect for solving that argument... just use the graph and you'll be in the right every time.
I had this exact argument with my parents about our wedding, my father wanted to invite his Aunt's and Uncle's (some I had never met) and really, since we were paying for the wedding, and I had never met them... sorry Aunt Ummmm... I can't remember your name. This is exactly why you weren't invited. Love you long time!
