You met an accident in the kitchen of your rent apartment. Write a letter to your landlord.

Dear Mr Lee,
I am writing with regard to give you some information about the accident in your kitchen.
Yesterday when I was cooking, a neighbour came to me and asked me to help her because her daughter had got sick. She is a new immigrant from Japan and did not know anything about the medical system in Canada. I explained that to here, totally forgot the pan on the fire in the kitchen.
When I went back to kitchen, I was shocked by heavy smoke and then I called 911 at once in case the fire is were out of control. Then I managed to stop the fire and I found that the wash machine and the microwave oven were burned and did not work any longer. Luckily there was no more damage caused, and I am so sorry about the accident.
I called the insurance company and claimed my loss as I bought full insurance before I moved in. They will come and evaluate the compensation tomorrow. I will fix it as soon as they pay for me.
I want to apologize again for my carelessness. Please feel free to contact me if you have any questions.
Best wishes.

Yours sincerely
Cindy Lee
