Really Depressing Poem

ALONE UNDER THE LAMP POST
No way is it easy, as much as it seems to be,
Gone past me a hundred times,
But still I failed to see.
Was a shadow, That was dark as night,
Was unfamiliar,abrupt, at times out of sight.
As I stepped behind, I saw it shrivel from mammoth to wee,
I discerned, the shadow was ME !
