One of my biggest pet peeves is when people leave a little of something in a container, box, etc and then put it back. I HATE THAT. It's annoying as hell to me. Fuck. You.
Here are some examples courtesy of things put back into our refrigerator with very little left in there.
This is a container of orange juice that was put back with that much juice left in there.
That's tea in the pitcher that was put back with that amount in there. I had to get level with the pitcher to get the picture because when I wasn't level, you couldn't tell there was any liquid left in the pitcher, lol.
If you're going to leave so little in there, why not just finish it? I don't get it. I hate when I open a cereal box and there's a handful of cereal left in there. Or better yet, a few pieces of cereal and a bunch of that dusty crap in the bottom. I could go on and on with examples but that would be pointless since y'all know what I'm saying.
While we're on the subject, another thing that really irks me? I hate when people don't close bags, boxes, etc properly. You took the time to open it, take the time to close it properly. It's not that freaking difficult. Fuck you, too.
I know these are relatively useless things to get annoyed over but seriously, it pisses me off. Especially the leaving the packages open thing. Stuff goes stale that way and not a lot of foods are still good after they're stale.
