Two days ago, I was havinghad a small accident outside of my homuse.

I fell down on the stairs and injured my arm.

The wound area looks terrible but it's not really (that) serious.

So, I still gowent to work yesterday.

But when all my colleagues saw my arm, they all said I should go see a doctor and rest.

In fact, that is the right thing to do.

So, today I gowent to see a doctor and tellold him about what happened.

At last when I asked him, can I have a day of rest at home?

He giave me 4 rest days!

But I told him 2 day is was enough.

I don't think you should write this as your conclusion as you were the one who said to minimise the number of dates. If you knew it would make you sad why do it? It could get the readers confused.
