Memorize this:

So he is mine, and in such bloody distance

That every minute of his being thrusts

Against my near’st of life. And though I could

With barefaced power sweep him from my sight

And bid my will avouch it, yet I must not,

For certain friends that are both his and mine,

Whose loves I may not drop, but wail his fall 

Who I myself struck down. And thence it is

That I to your assistance do make love,

Masking the business from the common eye

For sundry weighty reasons.
