We're going to play a game. Tell me "Start of Exercise" whenever you want. Once you do, I will keep the secret and I won't let you trick me. Tell me "End of Exercise" at any time, gladly, and game's over, I can discuss the secret freely again.
Though you may conjure, cast, or abjure - in my keeping precious secrets endure.
