Dear Roommate,
Thanks for putting up with me, because let's be honest living with another human is a big pain. As we have discovered living together I am not the cleanest human being, and sometimes I wait a week to do dishes. We have very hectic schedules and we don't always have time to hang out. That doesn't mean you aren't my friend, it just means we have to make effort and plan things. Living with someone for the first time has taught me so much. It has shown me how we all have rules and boundaries and we should always respect those. I learned that cooking can be quite the chore. I learned that there is a lot of responsibility. I appreciate all of the time that you give me, so that I can hang out in my room. I appreciate that you respect my boundaries, because all I want to do is the same. I know this letter is extremely long, but know that I appreciate all that you do while we live together.
