Let me describe my filing system for you.
I get a bill. I stack the bill on the desk. I pay the bill. I put the bill in a drawer. When the drawer gets full, I shred some of the bills. When the drawer gets full again, I put the bills in a box. When the box gets full, I push it up against the wall. When Tabitha gets frustrated with the clutter, I move the box to the garage. I don't know what happens after that.
I could write a book.
