I’d give all my tomorrows
for just one yesterday.
A day when I was young
before the world took it away.
When there were no cares
on my shoulders
and no worries
inside my head.
A day when life was free
and easy to live.
So, if I could give all my tomorrows
for just one yesterday
before my memories fade
and they are taken away.
