Nope? How can you possibly know with certainty what was going on with this man? You don’t know, none of us do. Everyone here is just Monday morning quarterbacking.
Nothing I said had anything to do with the windows having or not having a reflection. I used their experience just to show how easy it is to think you are 100% sure of something only to realize in a few seconds that you are totally wrong. They had a most definitive clue that there was no mirror and yet was so sure there was that they had to reach out to touch it. Unless any of those people were vampires, not having a reflection was a huge clue. There was NO mirror to confuse, it didn’t exist so “smoke and mirror” tricks doesn’t apply.
I am aware that sight problems can be considered a disability, not sure of your point. I certainly hope you are not implying that someone with a disability should not be caring for a child. That would be a horrible insult to many wonderful, fine parents.
And with all that said, I don’t think a lawsuit is necessarily warranted (unless the family is aware of something the rest of us are not) but I don’t think this poor man is guilty of anything except a tragic accident. It doesn’t have to be one or the other.
