I will share something very funny and unexpected thing which happened in my school days.
Back in 2017, when I was in 12th grade, one afternoon in school after lunch time got over, we were going to our classroom. Suddenly in the corridor, I did something crazy. I literally jumped on my friend named Joy from behind just for fun. He was really big built so I did it for fun and time pass. But he got very angry. He literally told me "f*ck off a**hole. If you do it again then I will kick your a**". I didn't take it that seriously and laughed and made funny faces at him. But I was shocked too because that was the first time Joy spoke so rudely with me and almost tried to beat me. Obviously his mood was bad because he is very tolerant and nice with others and how much ever childish things I did with him he always took them lightly. Then after I reached classroom he said "hey bro I am sorry for being rude with you". I forgive him and honestly I didn't take it seriously. I was just a little bit shocked. After that he never repeated it again.
