Can you use "please" in the following sentence?
"Could I please send you a letter?"
I always thought you can't use "please" when you ask someone a permission to do. There are only two types of questions that you can add please, I thought.
- Could you please take that book for me? (When you ask someone to do something for you)
- Could I get another cup of tea, please? (When you want something from someone)
Thank you for your help!
