Regret?

When I am an old woman and I can hardly see
And my limbs are as gnarled as an old oak tree
And naught but my thoughts are left to me
Should I regret the time I spent with thee?

When the tapestry of life has been spun
And sands of time have been outrun
And we feel as if we have just begun
Should I sorrow when our time is done?

When the end has come to us at last
And all of our life is in the past
And all that's left to us is fading fast
Could all that we had be surpassed?
