A conversation you have with a coworker or collaborator today will have a double meaning, although one of you might not realize it until it's too late. Speaking in code might be a great way of avoiding the wrath of nosy eavesdroppers, but it is a risky move: after all, unless both of you know the code you can't have effective communication! Opt for crystal-clear communications today. And if you need to keep a secret, just make sure you're talking in private.
