Olivia: What's a drunken man like, fool? Feste: Like a drowned man, a fool, and a madman: one draught above heat makes him a fool; the second mads him; and a third drowns him.
Love is a smoke rais'd with the fume of sighs; being purg'd, a fire sparkling in lovers' eyes; being vex'd, a sea nourish'd with lovers' tears; what is it else? A madness most discreet, a choking gall, and a preserving sweet.
