My 17th birthday was fun - went shopping and to a restuarant and all that - but it wasn't really a milestone for me.
I turned 18 earlier this year and even though that makes me able to go out drinking etc and is kinda seen as like the age you become an adult, I still don't feel much different. In fact if anything it's kind of annoying as I used to go to the cinema literally every weekend and get student tickets which were pretty cheap, but now to go to the cinema it's like...£8.50! And I can't spend that every weekend along with all the other crap I buy.
