I am a rag

I am but a wethered rag
seething in my rage
for when there is another rag
still my employment is engaged.

Scrub my face into the grime
that did not come from me,
Scrape my wrinkles all the time
to make not myself clean.

Crumple me and soak me now
in your murky water til I drown.
Until again I am revived
and again I'll grimly frown.
