Rising star

I'll turn up, the proverbial bad penny
Just when you think you finished me off 
And I am done with and gone forever
Though you want to get rid of me
You all who think you can shake me off
Like rain after a thunderstorm
from your raincoat
or snow you can brush off your coat
in winter
Like drops of sweat you flick off
And patterns on the window pane
Just a passing phase
But I'll be there, still, among the rising stars
Always, and all ways.
