Grocott & Ward, comps. Grocott’s Familiar Quotations, 6th ed. 189-?.
Regret
A feeling of sadness and longing
That is not akin to pain,
And resembles sorrow only
As the mist resembles the rain.
Longfellow.—The Day is Done.
For time will teach thee soon the truth,
There are no birds in last year’s nest.
Longfellow.—It is not always May.
For of all sad words of tongue or pen,
The saddest are these: “It might have been!”
Whittier.—Maud Muller.
