"CROSS THE LINE" is a fun game we play in Social Issues. 
   All the students stand on one side of the classroom.  Then 
   the teacher will ask a question like, "Cross the line if
   you have ever smoked a cigarette" or "Cross the line if 
   you have a dog."  Then, if you cross the line, you walk to
   the other side of the classroom.  It's always interesting
   to see who crosses the line.  You can learn a lot about
   people that way.  Since some of the questions can be very
   personal, anyone has a right to "pass;" the information is
   also supposed to be confidential.
