In two months' time l'll be starting university in Brighton. I'm going to tind somewhere to live next month, hopetully near the university, although I don'i mind being near the centre. I'm not keen on places ñear the sports stadiium it's very IOIsy! Will anyõne want to share a tiat with me? There are lots of ådverts for flatmates on the university website. I've wTitten to a few but I haven't had any replies yet. I've promised myself a new look" for my new life. Most of my clothes were bought in the sales, so they aren't very fashionable. I'm going to study mediá, and I'll be taughf by some famous journalists, so I'want to look moderm and stylish. I'm going to wear lipštick and nail varnish, and I'm going to change my hair. It'll be dyed red, or maybe blonde! I can't stand being dark-haired anymore. I might even get a tattoo -I'm not sure. I like some of Angelına Jolie's tattoos, but I don't know who they were designed by. Most people won't know me at university, so this is a great time to be different. Susannah is gong to be on my course, and she also wants a new style. She wants me to call her "Suzie", foo, which might feel strange. Luckily, 1 lıke my name! When are you starting university? Love from Maja
