Think of it like this:
* "Embarrass" has two "r"s. Imagine yourself so embarrassed you're practically *rolling* on the floor!
* "Embarrassed" has two "s"s. Think about the feeling of being *so* embarrassed, your heart is *sinking* and your face is *sinking* in shame.
This little story should help you remember the double "r" and double "s"! 😊
