A friend should bear his friend's infirmities.
What an absurd thing it is to pass over all the valuable parts of a man, and fix our attention on his infirmities. - Joseph Addison
So long as thou are ignorant be not ashamed to learn. Ignorance is the greatest of all infirmities, and when justified, the chiefest of all follies. - Izaak Walton
Let me advise thee not to talk of thyself as being old. There is something in Mind Cure, after all, and if thee continually talks of thyself as being old, thee may perhaps bring on some of the infirmities of age. At least I would not risk it if I were thee. - Hannah Whitall Smith
