yesteryear Nightmare by chasing unchaseable memory

i asked mr time a few question '' can you go back to 1 year ago??''
he answered '' why ? tell me why you want to go back ??? do you really miss those days??''
i replied '' some of it ....and ..i...i..i..just want to appreciate those days .............i'm full of regret and guilty''
he told me '' you should face it or correct it, not keep asking me of a favor that it is impossible''
he continued his speech '' by the way , i'm not time traveller ...even i manage to move my  clock's wheels to move backward ...do you think you wont do the same mistake or same things??'''
