Snatches from Lewis Carroll's

Valentine.
( Sent to a friend who had complained that she was glad enough to see him when he came, but didn't seem to miss him if he stayed away.)

"And cannot pleasures, while they last,
Be actual unless, when past,
They leave us shuddering and aghast,
With anguish smarting?
And cannot friends be firm and fast,
And yet bear parting?

And think you that I should be dumb,
And full DOLORUM OMNIUM,
Excepting when you choose to come
And share my dinner?
At other times be sour and glum
And daily thinner?

Farewell, dear friend, and when we meet,
In desert waste or crowded street,
Perhaps before this week shall fleet,
Perhaps to-morrow,
I trust to find YOUR heart the seat
Of wasting sorrow.
