The quality of a person lies in his/her cleanliness. Filth and dirtiness is the greatest sign of lack of quality. It shows that person's lack of common sense. How could a reasonable person not be disturbed by dirt? How could such a person not be uncomfortable about something that is sordid? If he/she is not uncomfortable that indicates a problem. Such a person cannot talk of quality. Such a person does not have any depth. - Harun Yahya
