Mail it to him in a locked box (you have the key). When it arrives, he should add a second lock to the box (and keep his key). Now he should send it back to you. You now, remove your lock and send it again. Finally he unlocks and reads your message with no chance for interception (or at least if it was intercepted, you would know because the locks would be cut off. We assume the post office can't apply their own lock that matches your key.)

Instead of sending him one message, send him two. The first one should be long and normal sounding, but its content is irrelevant. The second message, to be sent only once you're sure he's received the first letter, is a list of which words or letters in the first message should be circled, by row (line) and word (or letter) number. The circled letters comprise the message you intend. Unless you have some concern that the post office in question might have kept a copy of the first letter, they'll have no way to decode the message.
As an alternative, arrange beforehand that you both have the same copy of some book -- this book takes the place of the first message.
Does that work?

Puzzling, the responder just above, suggests the locked box approach. This was discussed on the podcast security now -try going to grc.com/securitynow to see the show list, transcripts and audio files.
The scheme is absolutely great, but, it IS subject to man-in-the-middle attacks because the locks could be taken off somehow and replaced with post office locks and then the post office can see the contents without the parties on the ends knowing. The post office would have to put the correct locks back on before forwarding the package though.
So you would need to use the scheme that Puzzler mentioned but also have _some_ way to tell if it has been tampered with.

ok - first of all, do no longer clutter the submit place of work with Royal Mail. You deliver the packet at a submit place of work outlet, yet later that very same day a Royal Mail postman collects it and it extremely is then interior the hands of Royal Mail, no longer the PO. If the postman tries to grant your merchandise, however the handle is incorrect / the handle is incomplete / the addressee has long previous away / the addressee refuses the object, he will placed a sticky label like this on it: (linked) and then return it to the sender. IF there is not any return handle on the exterior of the packet / envelope, the object would be sent to the Returns Centre in Belfast, the place a member of their team will open the letter / packet to seek for a return handle on the interior. in the event that they locate this, they are going to reseal it and deliver the object lower back to this handle. They technique thousands of things according to day, and the managers impose objectives and cut-off dates on them. they don't have time to study your love letter!

Use a code - maybe a simple cipher where A=1, B=2 etc.
Difficult to read, easy to break the code at the other end.

The post office doesn't read your mail, just the name and address.

or you can use fedex instead.
How is this a Math problem?
