You committed to a sum—not an explanation, not a delay. And by failing to take either your word or mine seriously, we can confidently say that this act of yours is a mistake. Naturally, everything that follows from it becomes a mistake as well.

This message is sent for one purpose only: to correct it. And the only way to correct it is by listening to me. So read the following carefully.

The only way out of this is to pay three times the original amount. In doing so, you buy your safety, your future, and the safety and future of those around you for that sum. I will honor that option from now until the next time we meet in person.

Consider this a warning given in good faith, and solely as a matter of fairness, so you have time to prepare. I strongly advise you choose that option over the alternative. Think carefully about the things you value most. You will never forgive yourself once you are forced to watch others carry the weight of your failure. That much, I know for certain.

In the world you choose to operate in, your word matters. Our word is currency. And when it is broken, someone like myself explains the exchange rate—the entire cost.

The only good that comes from these unnecessary acts is ensuring that people like you never make the same error again. It is how balance is maintained.

This is the last time we speak under these terms. If you choose to respond—by message or by calling me directly—it must be with the full amount and a time for delivery. Anything else is meaningless.

Until then, enjoy the days you have left before we meet again.
