The box never arrived. My mother thought I sent her nothing.
I looked back through my LJ. I sent out the box by priority on 12/9. It should have been there in 2-3 working days. That it hasn't yet arrived is a bad sign. Really bad.
It's highly unlikely I still have the receipt from the post office, even if it'd be any use at all. (I seem to recall it only having the price of shipping on it and my change due, no tracking numbers.)
This so, so sucks.
