The best-laid schemes of mice and men often go astray. He's the slave of all slaves who serve's none but himself. The willing horse is always worked to death. They that love must speak least. They're not all saints that get the name of it.
Empty barrels make the most noise.
A wild goose never laid tame eggs. Those that board with cats may count on scratches. He that talks to himself speaks to a fool. Better be a coward than a corpse. Calling names brakes no bones.
