A summer's day

Shall I compare thee to a summer's day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date . . . .

Shakespeare, Sonnet 18

Perennial

Be yourself. Especially do not feign affection.
Neither be cynical about love,
for in the face of all aridity and disappointment
it is as perennial as the grass.

- Max Ehrman, 1927
