Why Is My Little Sister So Smart?

Okay, so my little sister is like this annoying genius. I mean, seriously, she’s got a knack for math that’s just unfair. Last week, she solved one of dad’s puzzles in ten seconds flat while I was still trying to figure out which numbers were even. Now, don’t get me wrong, it’s cool and all, but it’s also kinda annoying because now everyone looks at her like she’s a prodigy. So, am I just behind the times or is there something seriously wrong with my little sister? Haha, jkjk. But seriously, advice appreciated!
