I'm moving.
That's a strenuous process.
I'm in the process of loading books into boxes. It's surprising how many boxes it takes for one bookshelf.
I've got a bunch of U-Haul boxes, which have flaps that need to be sliced in two places to fold them over.
The slicing, coming as it does right at the end, reminds me of cutting the butts out of fish when you're cleaning them. It's basically the last thing you do before tossing the fish into some cold water.
