He's Just Not That Into You

DEMETRIUS
Tempt not too much the hatred of my spirit;
For I am sick when I do look on thee.

HELENA
And I am sick when I look not on you.
(...)
It is not night when I do see your face,
Therefore I think I am not in the night;
Nor doth this wood lack worlds of company;
For you, in my respect, are all the world:
Then how can it be said I am alone
When all the world is here to look on me?

A Midsummer Night's Dream
Wiiliam Shakespeare
