My grandpa apparently wanted me to change my wedding date. My sister got a year long extension on a plane ticket that she couldn't use and it expires a week before my wedding. Silly think is that he didn't consider that since she's in the wedding party, she was planning on coming up 1-2 weeks early, so it's fine.
Luckily I had my Oma defending me, "No Gene, it's set in stone, the wedding date cannot change and that's the end of it..."
My date really couldn't change, we really only have 2 weeks here with a very low chance of rain before it becomes like 105 degrees every day, and that was the only available weekend for FH and I!
