The burnt child dreads the fire. - Ben Jonson

To speak and to speak well, are two things. A fool may talk, but a wise man speaks.

MOS: And besides, sir, You are not like a thresher that doth stand With a huge flail, watching a heap of corn, And, hungry, dares not taste the smallest grain, But feeds on mallows, and such bitter herbs; Nor like the merchant, who hath fill'd his vaults With Romagnia, and rich Candian wines, Yet drinks the lees of Lombard's vinegar: You will not lie in straw, whilst moths and worms Feed on your sumptuous hangings and soft beds; You know the use of riches, and dare give now From that bright heap, to me, your poor observer, Or to your dwarf, or your hermaphrodite, Your eunuch, or what other household-trifle Your pleasure allows maintenance.

But soft: I hear
Some vicious fool draw near,
That cries, we dream, and swears there's no such thing...
