pencil,pen,eraser

I was using a pencil,
my sister was using a pen,
my brother was using a eraser.
The eraser ran away,
the pencil ran away.
the pen ran away!!!
Suddenly the pen, eraser and pencil
bump to each other!!!
The went to my hand,
the eraser went to my sister's hand,
the pencil went to my brother's hand, and they are all happy
