Let’s face it: There are no set-in-stone rules out there for being a good person. Luckily, the people of Reddit are here to help. In a recent thread, people shared their top “unwritten rules” that they think everyone should be following in order to live a happier life. Keep these tips in your back pocket—they’re pretty amazing!

1. Be Prepared in the Bathroom

   “Buy a plunger before you need a plunger.”

2. Apologize Sincerely

   “Don’t mess up an apology with an excuse. Or say things like, ‘I’m sorry you got upset’ when you’re the one who upset the person. Take responsibility!”

3. Pee First

   “No matter what it is, pee first.”

4. Don’t Return Things in Disarray

   “Leave it in a better condition than you found it.”

5. Borrowing Someone’s Car?

   “Fill up the tank before you return it.”

6. Give People Personal Space

   “Not everyone wants to snuggle a stranger.”

7. Don’t Make Fun of Someone’s Laugh

   “Laughing is the most natural expression of joy and happiness and for someone to feel self-conscious about that because of other’s comments is so brutal.”

8. Stop Asking for the Last Piece

   “Don’t ask for something if the person only has one left. (Gum, cigarette, piece of cake etc.)”

9. Being Wrong is Okay—And Normal

   “You can be wrong. It isn’t a bad thing, either. And when you are wrong, acknowledge it, and learn from it, you don’t need to dig down in your beliefs to try and comfort yourself because you can’t handle not being right all the time.”

10. Canceling Plans? Reschedule

    “If you cancel and don’t reschedule, it’s often assumed you cancelled it not because you were busy, but because you just didn’t care enough about that friend. Rescheduling lets them know you do still want to maintain the friendship.”

11. Put Your Shopping Cart Away After Using it

    “There IS a cart return within eyesight and/or it doesn’t take that long to just take it back to the original stack by the store entrance!”

12. Turn Headlights on in Bad Weather

    “Turn on your lights in any sort of precipitation, even if you ‘can see ok.’ It’s not just to help you see. It’s to make you obvious to other people.”

13. Use Headphones

    “Don’t put your music on speakers when in a public space. It’s not like everyone wants the same genre or was in the mood for music.”

14. Chew With Your Mouth Closed

    “Shocks me how many adults I see chewing with their mouth open.”

15. Remember “Off Before On”

    “Let the people off the elevator before you get on. Let them out of the train, etc., so they can MAKE ROOM FOR YOU.”
