Dear Mr.nina

I want to apologize for my absence in your class yesterday. Also, I would like to make an excuse for what happened yesterday.

Yesterday before your class about 30 minutes, I was riding my motorbike slowly, then suddenly a car hit my motorbike in the back with a very high speed. I and my motorbike hit the road critically. I was injured badly but luckily a man took me into the hospital immediately. After checking my body, the doctor said my left leg bone was broken and I had to stay there in 4 days.

I have just wakened up for a moment, trying to write email for you to make you understand and pleased for my situation. Also, I want to ask you if you could allow me to absent your class until my bone is better.

I hope to see your response soon

Thanks and best regard
