Or thy affection cannot hold the bent.

'T is the curse of service,

Preferment goes by letter and affection,

And not by old gradation, where each second

Stood heir to the first.

William Shakespeare (1564-1616): Othello. Act i. Sc. 1.

You say to me-wards your affection's strong;

Pray love me little, so you love me long.

Robert Herrick (1591-1674): Love me Little, Love me Long.
