My younger brother did not studied properly due to his illness. So he was not able to write anything in the examination hall. Joseph, his class-mate, tried to help him by telling him the answer. Is Joseph was right? If not, then idiom "a friend in need, a friend indeed' will be wrong. If right, then it was against the examination rule. I confuse.
