“The best laid schemes o’ Mice an’ Men,
Gang aft agley.
An’ lea’e us nought but grief an’ pain,
For promis’d joy!”
— Robbie Burns
But according to Wikipedia: Although attributed to Burns, the Selkirk Grace was already known in the 17th century, as the “Galloway Grace” or the “Covenanters’ Grace”. It came to be called the Selkirk Grace because Burns was said to have delivered it at a dinner given by the Earl of Selkirk.
