I forget things even when I am not a zombie

I reached into my backpack today and found a sweater. I was packing to go visit cat.man for a night of homework and didn't need it so I pulled it out of the bag. About fifteen rocks tumbled out of my bag as I did so. I had forgotten that I'd seen the rocks while on my sketching adventure and decided it necessary to bring them home. Oh well. Covered in sand yet again.
