Monday, January 21st

I'm a virus (病毒) for the common cold. It has been a long time since I infected (感染) humans last time. Today I tried to infect a boy in a primary school all day.

His name is Sam. I waited on his desktop, and when he touched the desk I jumped on his finger. Unluckily, Sam didn't touch his eyes, mouth or nose. Then, right after class, he washed his hands. Now I'm full of soap and sitting in a sink!

This morning I jumped into the nose of Sam's best friend, Bill. Unluckily, the mucus (粘液) in his nose caught me. I thought it was over for me, when suddenly Bill sneezed while he was talking to Sam.

I knew that would send me right into Sam's face! However, Sam quickly gave Bill a tissue, and Bill sneezed into that instead! Infecting people is harder than I imagined.

I'm feeling very unhappy today. Some scientists caught my friend Harry and put him under a microscope. Harry is a flu virus and he's a dangerous little guy. Besides, Sam at all his vegetables today. He's exercising, ad he's getting eight hours of sleep every night. His body is too strong for me!

I tried to infect Sam again today, but he washed his hands five times and never touched his face! He also gave tissues to every student in his class who was sneezing. It's impossible to give him a cold! So I have to give up and I'm moving to another school.
