Somebody lost it

I found it

in the lost and found

I took it

gave it a new home

at first it was just a pencil

soon I had a full pencil pouch

then it was books

my once bare shelves

now are full

I own stolen school supplies

my library is full of stolen books

I call it borrowing

when I lose what I took

someone else will do the same

it will be a nice little circle

of finding,borrowing,and losing
