Having younger siblings guarantees your stuff will be missing more than it's actually in the spot that you left it. And if you're a female with a little sister lurking around, expect all your clothes to be MIA as soon as they come out of the laundry. While we certainly don't mind sharing, every older sibling knows that pure rage that overcomes you when you log on to social media to see your sister wearing a shirt they claimed "they hadn't seen in forever." Eye-roll.
