I would put the deed to the house and the insurance company stuff into a binder and run off.
Nope, according to the rules you can't take more than 1 thing. So you are only allowed to have exactly 1 drop of ink on that paper and no more, because that would be considered more than 1 drop of ink on the same paper.
And OP, you took a USB flash drive. That probably has a plastic casing, metal plug, and circuit board. According to the rules, you can only take one thing.
And why the hell could you only take one thing? Your house is burning, not being swallowed by a helldemon.
