Keep walking...
Just a bit farther...OK.
Pretend now that you take something out of your locker.
Pretend these lockers look a bit like cat cages, and are big enough to hold a tuba.
With the item in hand, now pretend that you turn around and start walking back down the hall.
Now.
Pretend that you hear a strange breathing raspy noise in your ear.
Let's just say that you take it very well...you jump and clutch your flute tightly and shriek.
Simultaneously.
You turn.
And BAM there's one of you classmates with a weird expression on his face, making strange raspy noises in a locker, who laughes his face off.
Lets say you take this very well.
You smash his nose in with your flute.
He lasted a few days, until one day I went out and all that was left was a wet spot and a orange peel on the ground. Dramatic death, no?
