Crazy person can be expected to act crazy.
This doesn’t mean a sane person is always sensible.
Distressed person can be expected to be incoherent (and should be).
This doesn’t mean a calm person necessarily makes sense.
Don’t give too much credit just because the person looks MORE creditable IN COMPARISON with it’s agitated version.
Just because something got better once, or ten times — doesn’t necessitate it got good enough.
Don’t make this common error of judgement. Be objective.
