nacho business
A question that's not needed, asked by someone who's too nosy and has nothing better to do.
Why did you break up with your girlfriend? You're not her, and you're not getting a free pizza.
Why do you know my favorite song? You're not my best friend, and you're not getting any of my money.
Why are you checking my phone? You're not my mom, and you're not getting any of my snacks.
