He who has been bitten by a snake fears a piece of string.
— Proverbs

We do not quite forgive a giver. The hand that feeds us is in some danger of being bitten.
Ralph Waldo Emerson bitten quote

If some confectioners were willingTo let the shape announce the filling,We'd encounter fewer assorted chocs,Bitten into and returned to the box.
— Ogden Nash

Mankind is like dogs, not gods - as long as you don't get mad they'll bite you - but stay mad and you'll never be bitten. Dogs don't respect humility and sorrow.
— Jack Kerouac

Quarrel not at all. No man resolved to make the most of himself can spare time for personal contention. Still less can he afford to take all the consequences, including the vitiating of his temper and loss of self control. Yield larger things to which you can show no more than equal right; and yield lesser ones, though clearly your own. Better give your path to a dog than be bitten by him in contesting for the right. Even killing the dog would not cure the bite.
— bitten quotation by Abraham Lincoln
