Course certificate and Rosie's story

Well, I did try to write something here yesterday at home but once again it chucked me out. So here I am at work doing this again.
Firstly, on Saturday I received a certificate of completion for the writing for children course I'd been working on. I thought I had to do 10 units but it seems there were only 8 which I'd sent off the week before. My tutor praised me for finishing the course saying I had patience and tenacity not to give up. I was determined to complete this course this time, as it was something that I enjoyed doing and interested me. I won't be extending it because I want to concentrate on stories and my book Bug.

Now I shall hand you over to Rosie Sullivan in my book Rosie and the Mystery School Bug.
Hi, I'm Rosie Sullivan and unlike most teenagers I know I like to live healthily by eating healthy foods and exercising. It comes from having a mum who manages a health food shop and a dad who is the sales rep. My sister Denise is not like me and won't be tempted to eat healthily but her time will come, I will make sure of that. Anyway, I thought that, apart from my family and close friends, no one was interested in my healthy lifestyle but I was wrong. It seems my school, which I thought was a normal school, is interested. It all started one Monday. When I left home for school that day my mum told me to do a good job for her. I thought she meant be a good student but later found out what she meant. In my PE lesson the hurdles I was about to jump shrunk lower to enable me to jump them easily, as usual our PE lesson made us late for French and I was surprised that our teacher Mrs Partain didn't say a word to me about it. Then at lunch I thought my eyes were tricking me when the unhealthy foods turned healthy. After that I had ICT and I got a message on my computer telling me to be aware of the eggs. It wasn't until Maths that I knew what it meant. Things got even stranger then. I got this huge headache and my eyes felt like they were burning me and in this ordeal I saw a vision of some boys come into our school and chuck eggs into our classroom. This is what actually happened and for me to predict this was totally strange. Class went chaotic then and to my surprise, me who is usually a shy person, stood up and took control of the class. Once I felt better and class returned, the lesson finished and then I got another message, this time from my Maths teacher Mr Holroyd, who told me that it was my time. Time for what? I mused. I was about to found out on Tuesday, when I confronted my Mum, who told me that I am special and that it was my time to help her and others put people on the right track about living healthily. What she meant by that I found out on Tuesday. Well, I thought Monday was strange enough, but wait until you hear what was about to happen on Tuesday and then after....
