I don’t have a sister. Most of the time, I’m jealous of girls who have a same-age perma-bestie to steal clothes from and bitch about their mom with. But occasionally, I’m just glad to know that no one is looking at me and someone who looks just like me, and debating which one of us won our genetic jackpot. Every pair of sisters you ever meet, you mentally decide which one is prettier, and that sucks. My heart goes out to poor Kylie. She’s a beautiful girl, and all anyone can say is that she’s not as beautiful as her supermodel sister Kendall. Except sometimes she is.
