“ But against sandfly fever one could be inoculated, and I have another, hideously vivid picture of a great menacing brute of a doctor sticking a Thing that ended in a vicious needle into my mother's arm. Mad to defend my own, I scrambled off my father's knee, and flew to her rescue. I fixed my teeth in the doctor's horrible hairy wrist and hung on like a terrier, until my father succeeded in prising me away. Afterwards, everybody said how wonderful the doctor had been, because he continued calmly giving the inoculation while I was prised off him, instead of breaking the needle in my mother's arm. But nobody said how brave it was of me, only three years old, when all is said and done, and gone in the legs at that, to take on such fearful odds for the sake of love. ”
