Is there anything weird with this paragraph? What if i said a very crucial letter in the alphabet will remain unused during the entirety of this passage? Can ya believe dat?! Usually in any letter, magazine, text, etc, this letter WILL be used, but I've carefully muted this letter.
..But i did make a single mistake (and by accident! but I figure this makes the riddle quite difficult with the added challenge. It is a very small, and if this passage is hastily read, it will be easily missed.) Where is it?
