Ghostly image? Coffee table? What is that in my picture?

 

This lovely lady is Delilah's best friend, Layla. In the top right-hand corner of the picture you can see a strange round thing that kind of looks like a face or something you might see under a microscope. The big debate between Layla's parents (Eric and Lindsay), Brad and I is whether this "thing" is some sort of ghostly orb, Lindsay and Eric's coffee table (which is made of a sort of wicker material) or something else. Eric and Brad firmly believe it's the coffee table. I find this pretty hard to believe as what's behind the "thing" is the window with the blinds down. I don't think it's humanely possible, at any angle, to have gotten the corner of the coffee table in the picture when the table is to the right and almost behind the ottoman Layla is sitting on. At first, Lindsay agreed with me that it was something else, but after a second look she thinks, although at a strange angle, it's definitely the coffee table. I still, after looking at this picture 10 times and showing it to a couple of co-workers, cannot see how it could possibly be the corner of the coffee table. How could the corner of the coffee table be half way up the window when there is no reflection because the blinds (which are a cloth-like material) are down!?!? Thoughts?
