You might not need to do all of these. Use your own judgment.
Step one: Move to another town (we’ll call this addresss B). Forward your mail.
Step two: After six months move to another part of town (we’ll call this address C).
Step three: Consider yourself doing the post office a favor and put in a forwarding mail request a week ahead of time.
Step four: This will confuse the postman and he, upon seeing a “strange van” in your driveway, will spontaneously decide to forward your mail two days early. You can thank him at your convenience.
Step five: While residing at address C, and still receiving forwarded mail from addresses A and B, prepare to move back to address A.
Step six: Put in a forwarding mail request for address C to address A. (But not too early this time. We don’t want them taking matters into their own hands again.)
Step seven: The panic will hit a few days later when you realize that you might never get your mail as it is now in a continuous forwarding mail loop.
Step eight: Call the Post office. Wait on hold. Explain the situation in as simple terms as possible, trying not to sound like an idiot. (It’s hard. I should know.)
Step nine: Listen as she reads you the instructions for fixing a “mail forwarding loop”. Do not interrupt even if you do have important and pressing clarifying questions.
Step ten: After clarifying, listen as she then re-reads the previous material.
Step eleven: Go to post office in person, even if the person on the phone said it could be fixed on the internet and ask for instructions on how to fix a “mail forwarding loop”. (Try to go when there are less people around. But only if you’re easily embarrassed.)
Step twelve: After receiving completely different instructions, take half of the previous instructions, half of the new instructions, mix them together and stick a dozen new forms in the mail (one for each step, apparently).
Now pat yourself on the back. You’ve earned it.
