Sep.30

I moved into the dormitory today—an ugly building and near a busy main road too.My room is small but quite pleasant.I must get some posters for the walls, though.I met a few fellow students at supper (the food was awful!)They all look much younger than me.They are, of course!

Oct.07

Lectures began last Monday.So far they haven't been very interesting (except for the man who lectures on drama.He's first class).Personally, I'd much rather go to the library and read, but I have to attend ten lectures a week.Those are the "rules"! Well, at least you meet people there.

Oct.12

I realiy don't like life in the dormitory at all.The food is bad and the students are noisy.They stay up half the night and play games just outside my room.When on earth do they sleep? When do they work? Besides, I don't like my room.It's just like living in a box! It looks even smaller now, with the posters on the wall.I am wondering how long it will he before I can feel as comfortable as I did living in my high school dormitory.

Oct.26

I tried to explain some of my problems to my supervisor today.She listened—but that was about all."You have to go to lectures, you know, Ann," she lold me.''And the dormitory is cheap and convenient." "Cheap and convenient"! Well.il isn't "cheap" if you can't eat the food and it isn't "convenient" if you can't sleep at night!

Oct.30

I can’t believe it ! Three other students—I met them at a lecture and they' re all about my own age—have invited me to share a flat with them.It's in an old house and it has its own kitchen, so   we can cook for ourselves.And my room—righy at the top of the house—is fantastic!

Nov.10

I moved into my new room last Sunday.I feel really happy.Life is going to be so much more fun from now on!
