On the eve of my brother-in-law's engagement, I lost my temper with him for the first time.
That day was also my 20th birthday. I smashed the cake he brought back to pieces. He slapped me, gritted his teeth and pointed at the door and said, "I didn't raise you so big to make you angry with me. If you make trouble again, get out of here!"
I ran away in anger, only to hear that he had canceled the engagement.
