They both have different lock and keys.

They each use a P O Box for thier Postal adddress and collect thier mail personally using thier key (or wait until the Postman goes on holiday lol )

Spot on Lucent-x well done.

Answer :

Derek sends a locked box with his letter to John.
John adds his lock to the box and returns it to Derek.
Derek gets the box, removes his lock and returns it to John.
John can now open box safely that has his lock on it.

Blimey my head hurts Wouldnt the phone have been easier?
