The following is news about some smart people asking for leave from their leaders.

Case 1

So-and-so (leader) is really sorry. Due to a sudden cold yesterday, I went to the hospital for an injection today. Now I am very weak and I really can’t go to work. Especially I'm asking you for a day off, I hope you will approve it. Then attach your medical records from the hospital.

Manager, I'm sorry, because my mother called me yesterday and told me that today was coming. She came to this city alone and didn't know how to hitchhike, so I want to ask you for half a day off to pick up her, is that okay?
