i totally snitched on my bro

sooo my brother has this huge collection of weird trading cards and he’s obsessed with them but i think they’re just silly and take up too much room in the house. one day we were cleaning and he hid a bunch under his bed, thinking no one would notice. well i saw it and thought ‘haha gotcha! ’ so i told my parents about it and they made him put them all away or give some to charity. i know it’s petty but i felt like such a sneaky genius. what was your worst sibling tattletale moment?
