Friendship is constant in all other things Save in the office and affairs of love.

I have unclasp'd to thee the book even of my secret soul.

He that is thy friend indeed,
He will help thee in thy need:
If thou sorrow, he will weep;
If thou wake, he cannot sleep:
Thus of every grief in heart
He with thee doth bear a part.
These are certain signs to know
Faithful friend from flattering foe.

Farewell, sweet playfellow.

...Who could refrain,
That had a heart to love, and in that heart
Courage to make love known?

Most friendship is feigning, most loving mere folly.
