The Mother-in-law Chronicles

What are the boundaries one adheres to when visiting someone in their home?  Does the visitor have the right to rearrange pictures on the wall just because they think a certain one would look better over there?  Do they have the right to go through the desk of bank statements and investment documents and move all of them out, putting them in a separate box and tucked away in another room?

No, the mother-in-law doesn't have this right.  I can tell you two things, #1 three weeks with us is toooo long and #2 the next time I am in Sydney, I am moving her shit around, just to piss her off.

Five days to go.
