how to mail letters for free

Who needs the “Forever” stamp when you’ve got this handy tip:
- Write the name of the person you want the letter to go to in the return address, where you’d normally put your address.
- Write your address front and center, where you’d normally put the recipient’s address.
- Casually “forget” the stamp.
- Your letter will be “returned” to the recipient and you, my friend, will have 42 additional cents in your pocket. Go nuts!

NOTE: as pointed out (so obnoxiously) in the comments, this is only likely to work if you live in the same state as the recipient.
ALSO NOTE: this is probably illegal.
yeah, cause when i put a california address in the return address and a massachusetts address in the “to” area and mail it at a post office in massachusetts, THEY’LL NEVER KNOW RIGHT? stupid, i thought of this when i was 8 and at the age of 8 realized it was stupid and easily disproven.
I’m there!
LOL!
