W: I keep washing your hand-napkins often.
H: So what?
W: They remain dark only, as if never were washed.
H: Could be because you are washing them in washing machine, where real rubbing does not take place.
W: May be, but I have done sometimes with my hands.
H: May be they are now old and can be recycled.
W: But, I am curious to know what are you rubbing and cleaning with these napkins?
H: Dark stains of my life.
W: Even if you are fully washed in the machine for 10,000 times, you will never become white, and stained-free.
