No underwear in this world can live without string and no string in this world can live without underwear ... because they are inseparable, they love each other, they are incomplete without each other ... that's why they have to live together ... they go together to Dhobi Ghat to get washed, they dry together and they get dirty again and go to Dhobi Ghat ... the world should learn the lesson of unity from the underwear and the string
