Nuh-uh, you don't!
I had a close guy friend once who revealed to me that when he was
in Sec School, his Chinese teacher took a liking to him. She
invited him to her home etc, giving him lessons outside the
curriculum. THey started off by her teaching him some calligraphy.
Then gradually, she apparently took erm... liberties with him.

I think that kinda scarred him. He was too scared and confused at
that time to know what to do.
Teachers who take advantage of their charges in this manner, ought
to be shot!
It's really not
funny!
