Trace your steps back. Find chunks of me. Do try to be smart. I go on forever, but the last safe holds my start. What am I?
I am the first of the last You'll find me in the forecast
Yesterday, of me does not know Unlike today and tomorrow
I have no regrets, you see And regrets has none of me
With no beginning and no end What do you think I am, my friend?
A full one puts a smile on your face. You keep on going like it's a race. But as my contents start to diminish, You'll start to think if you're ready to finish. What am I?
