I tell you what else is not uncommon: lying; attention seeking; twisting the facts to make them more interesting; being plain old mistaken; fantasizing; exaggerating; not realising an object was there the whole time before; noticing the object the night before in peripheral vision and that triggering a dream about the object; wishful thinking; etc etc.
There are many, many explanations for the nail story, Occams Razor giving us lots to choose from, including the least palatable but very likely 'it never happened' to the kinder and also very likely 'it didn't happen exactly as it was told to you'. Pick the simplest. It's the one most likely to be right.
At the absolute, rock bottom, doesn't-even-scrape-onto-the-list-of-potential-explanations you have "apported there by paranormal phenomena in defiance of all known physical laws and in the absence of an actual witness to the phenomena".
Will someone please explain to me where this drive, this compulsion to cling to a physically impossible explanation when there are so many well-document, human, possible, plausible and likely ones to choose from, actually comes from?
Tin Lizzie, I appreciate you believe you are keeping an open mind, but can you explain to me the difference between accepting "someone apported a nail" without question and just being a creduloid?
