When your spouse/friend/business associate says they did (or didn't) do it. Accept their word with full faith that they are being honest. Then go through their cell messages to confirm they are true angels.
Origin: Russian proverb, "doveryai no proveryai" (trust, but verify)
So he comes home late from work and doesn't feel hungry.
...So what did you say?
What could I do? Said, "Okay Honey" then checked his messages after he went to sleep.
...Do you think?
Naw, I mean, naw. Trust, but verify ensures a happy relationship.
