I attended a course a few years ago.
During the course the tutor gave us a coloured pen each and told us to write something POSITIVE about any person in the group.
Well this woman thought this would be an ideal time to slag me off.
On the board she wrote (in green) how she didnt like the way i talked and i was up myself.
I looked around to see who had the green pen.
I said to her "Thats not very nice for someone to write that about me".
She agreed and said it was awful.
I then pointed out it was written in green and she was the ONLY ONE with a green pen.
SHE RAN OUT CRYING
Moral of the story is dont try to outsmart someone who is smarter than you
