Hhm, this won't do. It'll have to be washed again.

What's up? Why are you smelling the laundry?

It appears the drying process was insufficient. Clothing that remains damp after washing becomes unsanitary and may emit a rather unpleasant odor.

Is that so?

Is this handkerchief also damp?

It has an unusual scent, but it doesn't smell bad, so...?

That would be my as-yet-to-be-washed underwear.
