This roommate goodbye letter can be used at the end of freshman year, in the dorms, or before a permanent move.
Dear {Recipient},
Man, time goes fast when you {party, work, study, etc.} as hard as we did. I am really going to miss you. My first day here, I thought I would be so lonely without any family or friends. And then I met you. Not only were you the best, most considerate roommate I could have hoped for, but you were a great friend as well.
I'm really excited that you get to go to {grad school, another country, etc.} I'm going to miss doing {activity} with you, though. We had some great times, and I hope you keep in touch while we're apart.
Let me know the next time you're back in {city}!
Sincerely,
{Sender}
