I have an older sister even though it doesn't really feel like it because the maturity just isn't there. She's two years older than me and always claims the only reason people assume I'm the older one because of my height. Which always makes it awkward. I really wish our relationship was better, but there's a lot of unresolved history there because she isn't exactly the most self-aware person in the world. Things kind of got better once I moved out, but I still can only handle being around her for so long before it starts to take a toll on me.
