Hi!

I'm so sorry, but I won't be able to come and help you fix your printer ©. I feel a disaster today - all my bones are aching, my eyes are watery and are aching too, and I have a fever. What could have happened, I wonder - I was perfectly

fit yesterday. W e walked till late with the guys from our school and

when I came home, I felt perfect. What worries me most is our maths test on Friday. I'll have to be there, otherwise my grades will be low ©. Any ideas on what can make me a new person again?

Sorry again,

Laura
