Luigi Pirandello said this quote

One gives way to the temptation, only to rise from it again, afterwards, with a great eagerness to reestablish one's dignity, as if it were a tombstone to place on the grave of one's shame, and a monument to hide and sign the memory of our weaknesses. Everybody's in the same case. Some folks haven't the courage to say certain things, that's all!THE STEP-DAUGHTER: All appear to have the courage to do them though.
