Classic Poem

Tongues there are that naught can say;
Tongues there are that run away;
Tongues that lure the fairies nigher;
Tongues that set the world on fire;
Bad's the tongue that rules his master;
Such lead ever to disaster.

Early make your tongue obey;
Always know what it will say;
Bid it say what you think best,
Hold it in for all the rest:
Fairies ban all tittle-tattle,
Wise men shun the tongues that rattle.
