but in the play the words form part of a speech of jealousy between childhood friends and the potential end of that friendship:
The scene in Shakespeare's original:
The fairy world - in the form of Puck - has interfered most clumsily with the passions of the human world, with the result that human lovers are confused in their loves:
Demetrius, Helena's lover, now loves her friend Hermia, who doesn't love him, and he ignores Helena, who loves him but is already becoming somewhat insecure about the powers of her feminine attraction.
Helena is therefore jealous of Hermia's beauty:
HERMIA
God speed fair Helena! whither away?
HELENA
Call you me fair? that fair again unsay.
Demetrius loves your fair: O happy fair!
Your eyes are lode-stars; and your tongue's sweet air
More tuneable than lark to shepherd's ear,
When wheat is green, when hawthorn buds appear."
