Call me irresponsible

Look back, was there anyone there?
Look back, did anyone care?
Look now, is anyone here?
Look now, why do you still shed a tear?
Look ahead, will you make or break?
Look ahead, is it just for convenience sake?

You say,
the past is the past,
the future is now;
but how can one let go,
if one doesn't know how?

I say,
if the time is right to be,
then there will be you and me;
and disappointments are part of life,
but together we will survive.
