Web Sheldon memory of footsteps

He was standing on the seventh floor opening the door
Welcome to life! he said
He was on the top of the game as it were
Welcome to the world he said, with a guff
One day, years later I heard quiet footsteps
Approaching slowly from behind
I turned around, we hugged each other
Welcome to time, I said
The great equaliser of all things
I know my little memory of footsteps will be
Swallowed into eternal oblivion
By the ruthless ocean called the Universe
But for now it's there with all its might
Like the death of a butterfly in the child's heart
My life, my love, but mostly love
Thank you for being here and now
Thank you for being you…
