Its so annoying! Well just call him 'he'. He leaves like 3 chips and a shitload of crumbs in case someone wanted them. He leaves a practically empty 2 liter soda bottle, with just those 5 nipples full of backwash on the bottom, he leaves one slice of bread in the bag which we can't see because the bread bin is on top of the fridge, so it goes unnoticed for a while, and I love the ends so that really bugs me, he leaves a drop of milk in the carton and opens the new one for himself, cus we might want the rotten drop in the other one, or he just didn't want to mix it with the new milk, he leaves hardly enough cereal for a tiny bowlful because it wasn't enough for the troth he eats it out of, he leaves about two spoonfuls of ice cream in the tub instead of just finishing it, he does this shit all the time!!! It really put my knickers in a twist!!! Is it normal that he always does this?????

I don't get it either. Half the time, it's like, why didn't you just throw the fucking thing away, it would've been easier than packing it back up and putting it back in the fridge or cabinet!! It sucks for when I shop too, there's been a few times I thought we had enough of whatever because I see the box on the shelf, come to find out the goddamn box has just a bit of dust in the bottom of it, and it's always something I was planning on using that night for dinner. Fucking retarded.
My husband had this thing I called a through he used to eat from too, it was this big ass serving bowl/platter thing. It was giant, it was ridiculous. I had enough of that shit though, it 'disappeared' one day, never to be seen again. That ended that.
You know what I don't get either? My husband will ever so carefully fold over the chip bags in such a particular and orderly way (it's the strangest thing ever!! always identical!!) yet is a complete fucking oblivious slob about everything else. Why be so careful and particular with a stupid chip bag yet can't tie your fucking shoes? What the fuck??
The only way to beat your husband is to play hardball. Don't replace any item if it is still sitting in place. This may not be practical with the milk. UHT?
Good luck!
