When I hit 21 the years just started flying by! I'm 26 now, and I don't know where the time has gone. I still think when I go to a club or to the off licence, that they are going to ask for ID. No such luck, they usually just wave me in without a second look, so I must be looking my age.
I wouldn't go back though and I wouldn't change a thing. There are lots of things I wish I didn't do etc, but I think they have made me who I am today, and I quite like me!!
