And, cousin mine, upon Monday is Saint Valentine's Day and every bird chooses himself a mate, and if it like you to come on Thursday night, and make provision that you may abide till then, I trust to God that ye shall speak to my husband and I shall pray that we may bring the matter to a conclusion.
And, we have Chaucer's earlier famous line from The Parlement of Foules (1382):
For this was sent on Seynt Valentyne's day Whan every foul cometh ther to choose his mate.
I guess the Medievals were not chicken about giving valentines. Sorry, had to say that....Take the poll on the side...Will you give or get a valentine?
