Twelfth Night

The unhappy, lovesick Duke Orsino tells his servants and musicians his love
If music be the food of love, play on; Give me excess of it, that surfeiting, The appetite may sicken, and so die.
Malvolio speaks these words after he finds the letter written by Maria that seems to reveal that Olivia is in love with him
Daylight and champain discovers not more. This is open. I will be proud, I will read politic authors, I will baffle Sir Toby, I will wash off gross acquaintance, I will be point-devise the very man.
I do not now fool myself, to let imagination jade me; for every reason excites to this, that my lady loves me
If you will not murder me for my love, let me be your servant.
Pardon me, sir, your bad entertainment.
Antonio is deeply infatuated with Sebastian, whom he saved from drowning, to the extent of following him to Illyria despite the personal danger to him.
O good Antonio! forgive me your trouble.
Orsino speaks these words as he discusses his love for Olivia with Cesario. Here, he argues that there can be no comparison between the kind of love that a man has for a woman and the kind of love that women feel for men.
There is no woman’s sidesCan bide the beating of so strong a passionAs love doth give my heart
Sir Andrew suggests challenging Malvolio to a duel, but Maria has a better idea: to play a practical joke on him. Leave letters lying around that will appear to have come from Olivia and will make Malvolio think that Olivia is in love with him.
