I believe you have my stapler
A line from a man who got his stapler taken and turned into a full-blown office drama. It's like when your little brother steals your snack and you turn it into a full-blown war.
I told my mom 'I believe you have my stapler' and now she brings me snacks every day.
My dog stole my stapler and I said 'I believe you have my stapler' to him. He gave it back and now he gets treats.
I said 'I believe you have my stapler' to my dad and now he doesn't take my video games anymore.
