GIVING BRAINLIEST! Write about anything you want, but make sure it is an event or feeling that is important to you. If you are writing about an event, write every detail you can remember, including the scenery and any dialogue.

For example, an event that is very important to me is my last baseball game ever, where I lost in the championship game during my senior year of high school.
Write as much as you can, but try to write enough to finish a page.
