If we highlight and paint the right window in red, then cut it from the original image, we can easily move it around the house. What I did next, I made this slice semi-transparent and placed it over the left window. I have to admit I was too shocked when I saw that both windows overlap perfectly. How did the landlord know this from the beginning? Did he construct the building this way on purpose? This is for us to ask, and for landlord to know.
