I completely know your shock the way you describe "you really wouldn't see this coming..." I knew a Special Ed teacher who was cool, calm, and collected...then LIKE THAT when I went to his apartment he started going down my shirt without even a hello...I was SHOCKED!!! He also claims he would go to the end of the Earth for people.....hmmmmm.....it's like one has someone's personality pegged, then, one often finds out how wrong they are.....personalities are complex things, I am beginning to see, more and more.....
