I gave you an example not even related to the document. Have I materially changed my Visa statement for the purpose of the House if I'm just trying to show an expense that I've incurred on my statement? I'm isolating an expense for their purpose.
Maybe I didn't want to show them, as I said yesterday, that I bought ceramic tiles at Home Depot for my bathroom—and I'm not doing that again any time soon. But if I want to block that out because I don't think it's of any consequence to my return to them, have I falsified that document?
