Don't cry over spilt milk.
— American Proverbs

Nothing is irreparable in politics.
Jean Anouilh irreparable quote

Many divorces are not really the result of irreparable injury but involve, instead, a desire on the part of the man or woman to shatter the setup, start out from scratch alone, and make life work for them all over again. They want the risk of disaster, want to touch bottom, see where bottom is, and, coming up, to breathe the air with relief and relish again.
— Edward Hoagland

Each man has his appointed day: short and irreparable in the brief life of all, but to extend our fame by our deeds, this is the work of mankind.
— Virgil

We get into the habit of living before acquiring the habit of thinking. In that race which daily hastens us towards death, the body maintains its irreparable lead.
— Albert Camus
