The Best & Worst Thing About Being a Youngest Sibling

Twitter user @mu11ff (iconic grumpy cat pfp, naturally) nails the youngest sibling experience:

"The funniest thing about being the youngest — you're desperately trying to act mature so no one treats you like a kid, working SO hard to seem grown-up... but then an actual adult stands next to your older brother and you just... collapse."

All that effort, undone in seconds by standing next to a real adult. The illusion shatters instantly. 16.2K retweets because every youngest sibling felt this in their soul.
