Anyone who proposes to do good must not expect people to roll stones out of his way, but must accept his lot calmly, even if they roll a few stones upon it.
— Albert Schweitzer

No matter how calmly you try to referee, parenting will eventually produce bizarre behavior, and I'm not talking about the kids. Their behavior is always normal.
Bill Cosby calmly quote

My cool judgement is, that if all the other doctrines of devils which have been committed to writing since letters were in the world were collected together in one volume, it would fall short of this; and that, should a Prince form himself by this book, so calmly recommending hypocrisy, treachery, lying, robbery, oppression, adultery, whoredom, and murder of all kinds, Domitian or Nero would be an angel of light compared to that man.
— John Wesley

Silent companions of the lonely hour,Friends, who can never alter or forsake,Who for inconstant roving have no power,And all neglect, perforce, must calmly take,--Let me return to you; this turmoil endingWhich worldly cares have in my spirit wrought,And, o'er your old familiar pages bending,Refresh my mind with many a tranquil thought:Till, haply meeting there, from time to time,Fancies, the audible echo of my own,'Twill be like hearing in a foreign climeMy native language spoke in friendly tone,And with a sort of welcome I shall dwellOn these, my unripe musings, told so well.
— Caroline Norton

A person in danger should not try to escape at one stroke. He should first calmly hold his own, then be satisfied with small gains, which will come by creative adaptations.
