It's nice to dream about ctrl+Z but really, going back has its own consequences.
Life has always its ups and downs. So when you are doing your good times over you cold be certain that the bad times are coming to be done over as well. Otherwise you wouldn't appreciate the good times at all.

I think that if I could I would go back to the times when I was doing my horseback riding and was spending every day with horses. Unfortunately this will also mean that I would have to be with my ex-ex and this will be truly tragic. This would also mean that his mother would be around and this could possibly result in either suicide or homicide. So no.... can't really go back to that episode.

Perhaps I would like to go back to that hot summer of 2006, when I was staying in Redfern during my time off, reading Haruki Murakami by the window all day long, waiting for that person to come back from work. I have never loved anyone that much before or after.
Only I can really tell how much this would mean to me.
Gosh.... anything to go back and do it over.... anything.
