I do exactly the same thing - except I always pick a random address in Canada for return.I picked a random address in australia and mailed it to there. I will bet that person was so confused. I also of course picked another very random return address in Poland.
Yes- These are the kind of things I do for fun in my spare time!
Nope. I have mailed a half eaten sandwich before. Then a few weeks later I sent a bill for it.
Both times I put a return address of another person whom I didnt really like too much. Its like spamming someone, but you boost the economy at the same time. You pay for an envelope, a stamp, this all goes into a mail truck, maybe on an airplane, a ship etc.... what an amazing way to impact the world.. and on top of that multiple post office workers get paid to sort and deliver this letter/package.. so you ensure their job security, that income goes towards their kids education, food on the table etc ... all while punking someones ass.
It's how I give back.
