Me: AUGH! Don't use that tupperware!
J.: Er... why?
Me: It's the cats' tupperware!
Me: It's the tupperware size set I use to store & freeze the cats' raw food when I make it because it's the exact size I need to properly divide for portions!* There are ten billion other pieces of tupperware in the cabinet.
J.: Oh, well, LOGIC. But I can't figure out what lids go to other things, so can't I just...
Me: ALL THESE TUPPERWARE ARE YOURS EXCEPT EUROPA. DO NOT ATTEMPT TO STORE THERE.
J.: *cracks up*
* I'd also like to point out that I specifically went out and purchased this set for this dedicated purpose, so it's not like I bogarted anything.
