The flies and filth

once i was sitting in my office in a hot summer day of June . the fan was one and i was having a cold drink while flies were buzzing around me with an irritating typical buzz and i was hitting them with my fly pad . it was like a mechanical action as the fly would come sit on the table and i would hit it with the pad and kill it and then throw it down the table with the same hit pad .
in comes of my peon unnoticed while i was hitting another fly on my table and asked me '' sir can i help '' ? i said no thanx man'' just these stupid fly are pissing me off'' . he then replied '' sir g they come on the filth dont kill them , just remove the filth and they wont come back '' .
i noticed what he was saying and i started cleaning my table and office all around and once i did that to my astonishment there were no flies around and it made me wonder
''we need to clean the filth around us in order to get away from flies'' .
