It is true that hypochondriacs very often do that behind a nurse’s back which they would not do before her face. Many such I have had as patients who scarcely ate anything at their regular meals; but if you concealed food for them in a drawer, they would take it at night or in secret. But this is from quite a different motive. They do it from the wish to conceal. Whereas the real patient will often boast to his nurse or doctor, if these do not shake their heads at him, of how much he has done, or eaten, or walked. To return to real disease.
