Unkind Words

I've been thinking recently that there are certain words in the English language that can't generally be used without causing grief for the listener. Consider "yet" or "still," as in

• "Are you looking for a job yet?"
• "Are you still working on your dissertation?"
• "Does she still have a lovey?"
  
• "Is he walking yet?"
• "Are you still living at home?"
• "Are you pregnant yet?"
• "Are you still on a diet?"

The list of unbearable (and unfortunately, very familiar) examples could go on and on. Of course, "should" and "never" could probably be added to my word list. But there's something about the feigned interest mixed with brazen judgment of "yet" and "still" that really gaul. At least users of "should" and "never" are very clear in their intent.
