Якщо вас не погладити, ваш спинний мозок почне всихати - Eric Berne

The destiny of every human being is decided by what goes on inside his skull when confronted by what goes on outside his skull.

But wether I am faking on a player piano, or striking the chords with the power of my own mind and hands, the song of my life is equally suspenseful and full of surprises as it rolls off the pulsating sounding board of destiny - a barcarole that either way will leave, I hope, happy echoes behind

In short, ‘Be careful!’ too often means: ‘Make a mistake so I can tell you I told you to be careful,’ and that is the final display. ‘Be careful, ha ha!’ is even more of a provocation. As a straight Adult instruction ‘Be careful!’ may have some value, but Parental overconcern or a Child Ha Ha gives it a different turn.
