embarrassing situation

Imagine this scene: you park your car and walk to a destination where you are going to have a meeting. It starts raining. You don't want to get all wet! You are one mile away from the your car now, which is where the your umbrella is., and one mile away to from your destination. You have two choices: run back to the car and get the umbrella, or continue walking towards the building. You are going to get wet no matter what you choose to do!

Fantastic job! While you were correct when you wrote "the car" and "the umbrella," since you are telling a story in the second person (you), it sounds more natural to use the corresponding possessive pronouns so it reads "your car" and "your umbrella."
