The greatest mistake is to think that we ever know why we do things...I suppose the nearest we can ever come to it is by getting what old people call 'experience.' But by the time we've got that we're no longer the persons who did the things we no longer understand. The trouble is, I suppose, that we change every moment; and the things we did stay.
