Is AUTHOR wrong in the post ? POST : A group of old college friends and I are going on a short vacation by the sea. We purposefully did not tell one of the group because - whilst they're a fine person and a good friend - they're a nightmare to live with. Without going into too much detail, they're very unhygenic and extremely arrogant. If they came, it would ruin it for everyone. We agreed not to tell them about the trip but we feel mean about it.
