It's easy to confuse words that sound similar. Most editing textbooks have lists of these mixups, and those lists include items such as:
- whose and who's
- presents and presence
- right, rite and write
- there, they're and their
- pore, poor and pour
The example above (from a CNN.com story on the sinking of a cruise ship) is one I haven't seen before. "Pal" should be "pall." "Pal" is a friend; "pall" is a sense of gloom. It seems like an odd error to make, especially since the words are not pronounced the same way.
