Dear Uncle Dixer: I have a double ceiling height foyer. I have a very large mirror placed on the side top of the foyer. When I walk in through the front door, it is on top left reflecting a very large arch window. The mirror reflects a chandelier and the outdoors which is a lot of greenery. Is this OK or should I move the mirror? 

Answer: As long as the mirror does not reflect the people walking into the foyer from the street, or directly at the street to reflect what comes in and back out again, it is fine.
