Shit on My Windscreen

The bird eats elsewhere,
But it shits anywhere,
While I park somewhere,
It decides to shit there.

Shit on my windscreen,
Makes my face lose the grin,
They should reduce the parking fee,
To cater for the bird's pee.

I have to wash the car twice a day,
This is really squeezing my pay,
And the government say,
It is a brighter day.

With shit on my windscreen??
