Private Quelch was a hardworking, simple-minded fellow. But he has some glaring negative personality traits. He was in the bad habit of showing off his knowledge. He would lose no opportunity to do so. Then he was quite tactless. He did not know that it was not good to interrupt one’s seniors in an effort to impress them. He was also ready to correct others in public. He was unaware that one feels embarrassed and humiliated if corrected before strangers. He was also a very condescending person. He would sometimes try to please his seniors by outshining others. All these character traits made him unpopular among both his seniors and juniors.
