The Cassette Recorder
Two people mike and angela are deeply in love but live very far apart. for her birthday mike wants to send angela a very valuable necklace but the posting system is very dodgy, the post service opens anything that can be opened or is seen to have value, packages can only be sent if they are locked because the posting people do not bother to open things that will involve time.
How can mike get his necklace to angela in a locked boxed when he can’t send her the keys of the lock because they will be confiscated?

Mike sends the necklace to Angela in a locked box with a padlock.when she receives the box she then puts a lock of her own on it and sends it back to Mike.when he gets the box he unlocks the lock he originally put on it, leaving the box still locked with the lock angela put on it.he then sends the box back to Angela and she can recieve the necklace by opening the lock that she put on it herself.
