The worst day in my life

I have an deeply experience with out of luck when I was twelve. That day, I forgot to bring my swimming suit when I went to the school team. The caoch told me to call my dad. When he arrived and bringing the suit, I got a scolding. Then the coach said I didn't concentrate my attention, so I got a scolding again. But the nightmare was just begining. I scored bad on my test and I talked to much in the class so my teacher wrote my communication book. When I was on the way home, my key slipped out of my pocket. In the evening, my dad punch me hard. I think this was the worst day in my life.
