William Allingham - The Winter Pear

Is always Age severe?
Is never Youth austere?
Spring-fruits are sour to eat;
Autumn's the mellow time.
Nay, very late in the year,
Short day and frosty rime,
Thought, like a winter pear,
Stone-cold in summer's prime,
May turn from harsh to sweet.

William Allingham
