Why is this still here?!

I've found several misplaced items in my house since we moved. One of the most random are the utility knives that are sitting on my kitchen counter. I have no clue why they are there. I look at them every day, probably 3-5 times a day yet never put them away. Why?

There's also some tacks sitting on the book shelf in the dinning room and some packing tape on the fridge.... I have no clue why I don't just put them away. It couldn't possibly be because every time I see them I am in the process of taking care of something for one of the impatient kids or cooking supper or something similar.  Oh well, I'm sure I'll take care of those things eventually...
