its good that you want to do good if given a chance to go back.
We all want to go back and fix things or either meet our loved ones for the last time or enjoy a past memory again.
Its would be soo rewarding but we al know it cant truly happen.
What we can do is live in the present and try to make the most out of it.?
I think that If I could do other things then just fixing things in past it would be working on my self giving my self a high school glow which I didn't really have
DO u have such ideas for past?
