Jumping on my Shadow

One sunny afternoon,
in Sunday best and
banned from play,
I spied it mimicking
whichever way I moved.

Thus tantalised, I sought to jump
upon the wayward thing,
but always as I moved to leap,
it danced aside again.

It never would be caught!
Has teased me many a day,
mimicking the foolishness
of my pretentious play.
