Marry, by these special marks:  first, you have learned, like Sir 
Proteus, to wreathe your arms like a malcontent, to relish a 
love-song like a robin-redbreast, to walk alone like one that had 
the pestilence, to sigh like a schoolboy that had lost his A B C, 
to weep like a young wench that had buried her grandam, to fast 
like one that takes diet, to watch like one that fears robbing, 
to speak puling like a beggar at Hallowmas.
 — William Shakespeare
