6 Americans joined our medical mission on the 3rd day but only 2 are doctors. The 2 doctors did not bring along even a stethoscope and asked for help. I joked that we should give them each 2 paper cups with a string attached at both ends as a substitute. We had a good laugh. When you're weary and missed the comfort of your home, a sense of humour certainly helps to lift your spirit. I later learnt that one of them is a pathologist and the other, a neonatal orthopaedic surgeon. No wonder they don't need stethoscopes in their practice.
