I've followed this since I first heard of it, and, from what I've seen, I've got to say that I concur with Kaijima. I've had to deal with the "Oh, no, everything's okay" people before -- I bloody hate it. You never find out what's wrong -- or that there's something wrong -- until long after it's past the chance to correct it.

It's not your fault if the person won't make their opinion known to you.
