You did everything right and it went down anyway.
Say that plainly, once, and stop hunting for the mistake.

The hunt is not diligence. It is a way of keeping discipline in charge of something,
and discipline is not in charge of this,
and has not been asked to resign.

Some facts are not addressed to you.
Go in anyway. Go with a lighter bar and the same face.

The Book of the King — Wall 45:9
