There are ways to work around this.  The key is to not lie, but to tell a <i>different</i> truth.  I used to do this in high school, when my parents were grilling me.<p>Friday night: go out with quiet friends.  Saturday AM questioning: &quot;How was your evening?&quot;  &quot;Fine&quot;.  &quot;OK&quot;.<p>Saturday night, go out with less quiet friends. :)  The Sunday AM questioning was rather more rigorous.<p>So I described what I did Friday.  There were telling hesitations, of course.  But 90% of the questions had immediate and honest answers.  Just with the day changed.
