Wit ever wakeful, fancy busy and procreative as an insect, courage, an easy mind that, without cares of its own, is at once disposed to laugh away those of others, and yet to be interested in them – these and all congenial qualities, melting into the common copula of them all, the man of rank and the gentleman, with all its excellencies and all its weaknesses, constitute the character of Mercutio!
I could not have said it better than Coleridge.
