Quote #1
CASSIUS
Brutus, I do observe you now of late.
I have not from your eyes that gentleness
And show of love as I was wont to have.
You bear too stubborn and too strange a hand
Over your friend that loves you.BRUTUS
Cassius,
Be not deceived. If I have veiled my look,
I turn the trouble of my countenance
Merely upon myself. Vexèd I am
Of late with passions of some difference,
Conceptions only proper to myself,
Which give some soil, perhaps, to my behaviors.
But let not therefore my good friends be grieved
(Among which number, Cassius, be you one)
Nor construe any further my neglect
Than that poor Brutus, with himself at war,
Forgets the shows of love to other men. (1.2.37-53)
It's obvious that male bonds are a big deal to the characters in the play. When Cassius asks Brutus why he's been so distant lately, Brutus goes out of his way to apologize to his pal for neglecting their friendship.
Quote #2
CASSIUS
And be not jealous on me, gentle Brutus.
Were I a common laugher, or did use
To stale with ordinary oaths my love
To every new protester; if you know
That I do fawn on men and hug them hard
And after scandal them, or if you know
That I profess myself in banqueting
To all the rout, then hold me dangerous. (1.2.77-84)
Here Cassius tries to convince Brutus that he would make a better leader than Brutus' friend, Julius Caesar. Although Cassius claims he would never try to manipulate a friend, his excessive flattery seems to suggest otherwise.
Quote #3
BRUTUS
I would not, Cassius, yet I love him well. (1.2.89)
When Cassius asks Brutus if he would want Julius Caesar to be crowned king, Brutus says that even though he loves Caesar, he doesn't want him to be a monarch. (Remember, the idea of a monarch ruling Rome with absolute power went against the ideals of the Roman Republic.)
