This came to be from just a random neuron connection
Ever wondered what happens when you post a letter in the mail box with your address on the front (To: address) and the address you actually want to send the letter to on the reverse (From: address) return address area? If you just want the letter to reach it intended destination without a stamp on, you think where will the letter go to? And will you ever lose it?
P.s I won’t be foiling your next possbile plan to send christmas cards to all your friends for free, but I won’t be responsible for anything arising from the use of this thought. You know how it will work, be responsible, do at your own risk! What’s more it’s only $0.20c you are trying to save, spare a thought for our friendly postmen.
