It is so hard to understand why or how any teacher would cross over that line. There are so many venues that would allow an adult to indulge in inappropriate sexual activities - why pollute a young student? Likewise, the mannerisms and presentations of a teacher (either male or female) must be constantly controlled in order NOT to give any student(s) the wrong impression. Unfortunately young students are often sacrificed by people who are obsessed with their own self satisfaction. Everyone loses in this game.
