I may not choose to go back to being sixteen now, as i am curious as to were the path if i have for myself leads to.
But, if a genie or some sort of god came and found me at my deathbed, or moments before death and said he could take me back to being sixteen again, then hell, i defiantly take that chance and live two lives instead of one.
I would make the most out of the time i had with my ex-gf, i would change a few suitable things though, basically to make the experience more enjoyable and memorable. I'd still have to dump her in the end though, but i'd try to manage the break up better so i can still remain on talking terms with her, if that is ever possible. I'd also bug my dad to get his old work laptop sooner, and look after it better- don't click on that link that gave my laptop a virus.
I'd re-enjoy that summer holiday after my A-Level's, i wouldn't change a thing there. Come university though, i'd skip the first Debating Society meeting and not miss the first Rock Society meeting, as well as not get a sudden and horrible bout of home sickness which meant i missed the gamesoc meeting as well. That way, i'd miss a lot of depression from the first year of university, and wind up with some completely different friends. Then, one can only imagine how different my university experience would have been.
