My sister gave me a wedding gift list of five luxury items. Take all five or don't show up

"Buy all five of these luxury gifts," my sister demanded, "or simply don't show up." I tossed the list in the trash and completely ignored her invitation. She convinced our parents to threaten my inheritance, crying to the whole family that I was trying to ruin her dream wedding out of jealousy. I used the gift money to book a first-class trip to Hawaii for myself, making absolutely sure I "simply didn't show up."
