Pencils are funny things.
The reason why pencils are funny is because they always disappear when you need them as most.
I have gone thrue at least 12 pencils this school year.

The conspiracy

I think that the teatchers are involved.
They say that they don't want to be disturbed, but really they do want to be disturbed.
They are lonely in the teatchers room and just love when the students comes in and ask for a pecil.
They must be opening the lockers at night when the pupils are at home.
It is a conspiracy!
This also inwolwes rulers, erasers, books, paper, and in some cases even chewing gums!
