   Summary

   Your name is Robin, you're a 18-year old senior in high school. You get a surprise visit from your older sister, Catherine, on a random Saturday in October. The two of you have always been close, both being each other's rocks through your transitions. Catherine brings you skating, and you two bask in each other's presence more than you'd ever imagined you would.
