Love – That’s All Cary Grant Ever Thinks About (1964)
Context: I never dwell on past mistakes… There is too much to plan for the future to waste time complaining. Elsie Mendl was a great friend of mine for many, many years. And I remember the creed by which she lived: Never complain, never explain. Just think of the people you know who are always explaining their mistakes. It merely rubs the whole thing in. You’re reminded again of the mistake. And no one believes the explanation anyway.

Context: Explanations are clear but since no one to whom a thing is explained can connect the explanations with what is really clear, therefore clear explanations are not clear. Now this is a simple thing that anybody who has ever argued or quarreled knows perfectly well is a simple thing, only when they read it they do not understand it because they do not see that understanding and believing are not the same thing.
“I believe there’s some explanation for this universe, which you might call God.”
