Never lie to a child about doctors or medicine or anything else; but if you feel, as some people seem to feel, that life without lying is an impossibility, at least don't lie about the amount of pain likely to result from a surgical procedure, or about the taste of some medicine. If you know that something to be done will hurt, say so; if a mixture to be swallowed is unpleasant, say so. If you deceive a child once in such matters, do not imagine that it will trust you again. You do not deserve trust, and you will not get it.
