Turning back time

Have you ever wished you could turn back time and redid things differently?

Have you ever wished it so badly that you felt time was truculent to be a universal dimension, 1-direction-vector that went perpetually, never folded and never stopped, and the tip of your hand seemed to be able to touch (even if in the most faintest way) what's older than present, but it was meant to tease you because you knew it was unattainable?

I wished it. Lotsa times.

Maybe I'm not regretting my life. I'm more than aware that millions of people of my age (or even more) are not as lucky as me. Not a lot of people have chances.
Maybe I'm regretting what I'm doin with some part of my life (though not a lot).
Sometimes "late" is real, that something done wrongly be damaged permanently once the time for the call has passed.
