The third essay is the most enjoyable to write from my experience: The letter to your future roommate For this essay, I've found that it doesn't hurt to make a few jokes or be silly if you're that kind of person. On the other hand, if you're normally a more serious person, then be serious. I'm normally more of a silly person so I started off the essay writing about my skills in the "art of laundry." You should really treat this essay as a letter you would want your future roommate to read. With this in mind, I've found that very few students I know used this essay to highlight more of their accomplishments. You've done enough of that in the rest of your application. Use this essay to expand on the things you weren't able to list in the second part of the supplement (ex. Your favorite hobbies) and then reveal more about who you are as a person in your nonacademic life (ex . Your likes, dislikes, any of your quirky habits).
