Dear Annie,
I feel betrayed by my friend,Hannah.We have been friends since primary school and spend almost every day with each other.Sometimes,other children say we are no fun because we are both very academic and like to study,but we like it that way.We are both very hard-working and we both get good marks at school.
On Monday,We had a surprise Maths test.I thought it would be quite easy and was not worried about the results.I must have sounded very proud of myself after the test,saying loudly how easy it was and how I was sure to get a good mark.The next day after class,my maths teacher told me that I had scored the lowest mark in the class!I felt so ashamed; I must be really stupid if I couldn’t even pass an easy Maths test!I didn't feel like I was overlooking my studies,but maybe I could work harder in maths.
Afterwards,I went out to the playground.I was determined to be cheerful,but Hannah sensed something was wrong.We went to wash our hands in the girls' toilets before lunch and I admitted how badly I had done.I made her promise not to tell anyone,and she said she would keep my secret.
However,the next day,I noticed that my classmates were staring at me as I came into Maths class and when I went to sit down,I found a piece of paper on my desk that said "Stupid Sarah got a " I was so upset that I felt like crying.I thought that Hannah must have deliberately told everyone about my mark after promising not to.How they must have laughed behind my back!
I was so angry that I went straight to Hannah and told her we weren't going to be friends any more because she couldn't keep her word.She was really upset and swore that she hadn't told anyone,but I know that the only people who see marks are the teacher and the student.She said that someone must have heard us in the toilets,but I don’t believe her.I don't think I can ever forgive her.Now I've lost my best friend and everyone teases me.What shall I do?
