Interesting.... I find myself throwing away a bit of extra rice that doesn't fit in the canister. Listening to the radio while sorting the kitchen; cbc news tells of people starving in Pakistan.
I decant rice purely for ease of storage - bags are floppy and my cupboards work best with uprights. In essence I'm throwing out the rice so it won't clutter up my pantry.
I briefly wonder if that is a sin, as I take it out to the trash.
