Dear Current apartment owner,
I understand this is not the letter you were expecting to receive. My name is Richard Collenal, I am 26 years old and my current time is November 14th, 1936. I am your new roommate. Or not exactly new. I expect you'll move out after reading this letter, as the last six people have done. I understand, depending on how many years have passed in your world, that you are from 2020. We will most likely never see each other in person, and you may not even receive this letter, but here you are.
Stolen story; please report.
I hope to see a response from you soon, or even a notice that you are moving out.
No, this is not some schoolboy joke.
Have a lovely day, roommate.
Sincerely,
Richard Collenal.
Nov. 14th, 1936.
