How to write what I want to say to you?

The format of what I want to say to you is: start with a fixed frame and write the person you want to talk to. For example, if you want to say it to your mother, then the format is to write a fixed frame of what I want to say to you, mom, followed by a colon, and then start a new paragraph, starting with Leave 2 spaces blank to write in detail what you want to say to your mother.
