A special kind of time-delay envelope is in circulation.
Write a letter now and send it off, and your future self is guaranteed to reply a year later.
The time-delay envelope has rules known only to a few:
1. The reply will only repeat what is destined to happen. It won’t offer a solution.
2. No matter how you try to avoid it, the event will happen. Only the way it happens can change.
3. It cannot rewrite cause and effect; it can only let you know the ending in advance.
4. The envelope works in one direction. You cannot go back in time and interfere.
Premise: Take every day seriously
