How can you rewrite the following sentence from the first-person perspective of someone in the sentence?: He was riding his bike when the kid threw a football at him.
"I was riding my bike when a kid threw a football at me."
"He" and "his" indicate that the sentence is from a third-person perspective. To change the sentence's perspective, you would have to replace those with first-person pronouns like 'my', 'me', or 'mine', depending on the context of the situation.
