Do not wear a jean jacket when wearing jeans because people will talk about you.
When the person next to you asks for a pen, don't give it to them. You will probably never see that pen again.
If your parents tell you not to be friends with someone you should listen to them. They can see fake friends before you.
If your friend is wearing the same thing as you, try not to choke them. Just don't talk to them for that day.
If you had the choice to study for a geometry test or to go to a party, go party. Polynomials and angle pairs won't matter in the future.
When putting on makeup, make sure your winged eyeliner looks perfect. Or you will look like a panda/bat.
Always ask your siblings before wearing their clothes. You wouldn't want to end up in a fistfight with them.
