The Secret Hoarder

I know my little sister looks up to me and thinks I’m so cool and responsible. But deep down, there’s this hoard of candy wrappers hidden in my closet that’s been growing for months. Every time she brings home new treats from school or a party, I sneak them away, just because they’re my favorites and I can’t stop myself. I feel bad about it every single day but still do it anyway. What kind of big brother am I?
