Remember that time as a kid you tried sending a birthday card to your grandmother and wrote the wrong address on the envelope?
Okay, so maybe you didn’t do exactly that, but there’s a good chance someone else reading this (or writing it) made a similar mistake. In the end, grandma still loves you and there’s proof of your effort if the card was Elvis Presley’d and returned to sender.
This would be much less amusing if you had to ship jewelry instead of a birthday card. It would be maddening if the address was to an opportunistic criminal instead of a non-existent address.
