I found a way to save 39 cents

[David Brent]

I'm currently conducting an experiment in hopes to save money. When I want to send a letter via mail, I will put my name and address in the middle part of the envelope. I will write down the return address of the person I want to send the mail to on the upper left corner of the envelope. All I would need to do is to mail the letter and hope for the post office to "return" the letter to the person I want to send the letter to without having to pay for stamps.

What are the chances do you think I have of succeeding this kind of experiment? I will keep you updated on how it turns out.
