You look like you've been to the open-air market. Buying fresh flowers and fruit with a foreign currency. You spent your Saturday morning converting weight and worth into something you could recognize.
You've done that in your life too. The unknown? Very heavy but worthless, big fat coins you carry. The truth? Heavy and expensive, bars of gold you keep hidden away. Lies? Lighter than the air that carries them and cheaper than anything, play money - the paper and ink of your life.
The old woman selling honey murmured as you walked by her stand at the end of the market. Leave the market without regret, she said. It'll cost you more than you have. When you die, and you've already started, regret will not hold your hand.
