I am free from worry.

Worry has a superstitious quality that almost nobody admits to. Somewhere underneath, attending to the bad outcome feels like what keeps it away — as though letting go of the results, or the flight, or the person driving home late, would mean dropping the guard.

It is an unusually expensive amulet. It works on nothing and it charges by the hour.

The test is simple enough. Is there an action inside this? If so, take it. If not, then it is not doing the job it claims to be doing, however faithful it feels while it runs.
