I think the one KeY finds most annoying now:
8. Looking up information while a discussion/argument is still in progress - So what are laptops and mobile phones for, if not to resolve disputes or questions wherever you happen to be? Why would anyone get annoyed when you pull out your iPhone in the middle of a discussion about, say, a news story, and a minute later break back into the conversation with the details of the story that everyone else had forgotten? Yeah, it beats me, too, but my wife insists this belongs on the list.Yup. She hates this!
