Every dealer cracks up his wares. [ German Proverb ]

And conscience, truth and honesty are made
To rise and fall, like other wares of trade. [ Moore ]

Daughters and dead fish are no keeping wares. [ Proverb ]

When the wares are gone shut up the shop windows. [ Proverb ]

If fools went not to market, bad wares would not be sold. [ Proverb ]

Some are so close and reserved that they will not show their wares but by a dark light, and seem always to keep back somewhat; and when they know within themselves they speak of that which they do not well know, would nevertheless seem to others to know of that which they may not well speak. [ Bacon ]
