Not really a note, but when I was teaching college classes, I caught two of the girls whispering, so I told them “If you’re going to tell secrets, you need to share with the rest of the class.” (I taught preschool before this). She looked right at me, and said, without the slightest embarrassment, “I was just telling her that I think you have a cute bu@#.”
I was teaching a Communications class, and we were discussing communications in the workplace, and I looked down at the textbook. After seeing what the next section was, I said “Ok, moving on to the next section, titled ‘Sexual Harrassment’.” Everyone roared with laughter.
A couple weeks later, at a baseball game paid for by the school, she came on to me really hard, with my fiancee right there.
