It makes me happy to hear that, Jude. I do like it when someone takes notice.
And, no, you can't claim to have an explanation. But even if you gave up, to say that there is no explanation ( as opposed to saying you were unable to find an explanation ), is still a cop-out of enormous magnitude. Because explaining something that defies explanation is by definition impossible, the best you could do is continue to look for the explanation, and meanwhile, even if you never find it, admit that there may still be one.
