Fun fact: the Korean word for “apple” also sounds like the Korean word for “fight”. The word is 사과 which is pronounced as “sah-gwa”. Schools around the country celebrate Apple Day as a chance for students who were fighting to make up. Just give your previous enemy an apple and all is forgiven.
It is also a chance for students to suck up to their teachers, which I am perfectly fine with. They wrote me a cute note to go along with my apple.
Personally, I think giving apples as an apology is a great idea. If you have someone you want to say sorry to, just give them an apple. Life is too short for fighting =D
