3. "Don’t leave your shopping cart in the middle of the grocery aisle!"

—u/M3ggsandbacon

4. "Never make fun of someone else's laugh — be it how they sound or how they look. Laughing is the most natural expression of joy and happiness, and for someone to feel self-conscious about that because of other people's comments is so brutal."

—u/ArthurMcSlothington

5. "If you have to cancel on a friend, it should be your responsibility to reschedule."

—u/Havoo

6. "Don't propose at someone else's wedding."

—u/LongliveLazarus

7. "Don't ask for something if the person only has one left (gum, cigarette, piece of cake, etc.)."

—u/anothersocialoutcast

8. "Be kind to people who are working: food staff, medical staff, etc. Don’t take your bad day out on someone else."

9. "Don't look through the fucking gap of bathroom stalls."

12. "For buses/trains/any other public transportation, let people exit first before you get on."

—u/miaowies

13. "Don't say shit about someone's appearance if it can't be fixed in less than 30 seconds. Spinach in someone's teeth? Let a homie know. Body type? Bad haircut? Worn-out clothes? Don't need to mention it."

—u/vaguelyhumanpotato

14. "Leave it in a better condition than you found it."

—u/Essexal

15. "Don’t mess up an apology with an excuse."

—u/MHE17
