It is, it is: hie hence, be gone, away!
It is the lark that sings so out of tune,
Straining harsh discords and unpleasing sharps.
Some say the lark makes sweet division;
This doth not so, for she divideth us.
– William Shakespeare
Romeo and Juliet, Act 3, Scene 5. Juliet finally agrees that it is morning and Romeo, who has been banished from Verona, should leave. She is afraid that if he stays he may be caught and killed.
