ISN'T IT SO

Why do the tree frogs scream
From dusk till dawn
As if they are being tormented
Driving me to close the
porch door
and cover my ears.

Why do the tree frogs
Sing like a heavenly choir
While I linger on the
porch a little longer
Just before I sleepily amble to my bed
Falling asleep peacefully
Content in the angelic sounds of God's creatures.

They scream when I'm screaming
They sing when I'm singing

ISN'T IT SO
