Where is the Past?

Screaming sounds across the sky, silent as a buzzing bee fly

Chanting rhymes I used to know, reminding me of long ago

When my smile was worth a while,as I walked along the Nile
Spring is come everyone says, but all I see is winter's face
Where lives the trees amidst this freeze?
Where is the ass eating green grass?
Where is the past I cried at last
That place where I found embrace
