Yeah guess what happened
It wouldn't be right for me to sit here in front of you and say "I'm worried." It would be wrong because first, it would require that I track you down so I could sit in front of you, and despite living in a relative golden age of world travel, that's just not going to happen. It would also be wrong because the emotion I am currently feeling--as are, I'm sure many of you--is not worry. It's something else.
I've been trying to think of the English word for this emotion, and to be perfectly honest with you I'm not sure that one even exists.
