Urine So Much Trouble

(I am a 15-year-old female and my little brother is 7. My mom has an annoying habit of making him pee in a cup instead of stopping the car. One day I enter her car with them both for a shopping trip. I notice an opened can of soda in the car’s cup holder. My mom likes to drink soda in the car while she drives.)

Me: *grabs it* “Perfect. I’m so thirsty.”

Brother: “Wait!”

Me: “Why? You’re not getting some.”

Brother: “No. I peed in there yesterday!”

(I drop the can back like a hot potato and glare at my mom. She got an earful from me that day for me nearly drinking pee!)
