Everything seems to belong to Oribel. There is a difference of opinion on this matter however. Since Hubband and I don't happen to think that the clean dishes are hers, the stove, or anything in-route to the stove, we have had a minor rearrangement of stuff on the counter top. We moved the microwave to the edge of the counter at an angle so she can't get past the front of it. The angle is so she can't get around the back of it either.
Apparently, because everything is hers, I need to do some work on the "going over the top" aspect of getting to her belongings.
