This Week's Best Moment in Teaching

As all of you know, every Wednesday I teach two 15-year-old girls. I’ve lately gotten them to speak more and caused more than the occasional eruption of teenage girl laughter. Their comprehension, especially while listening to native speakers, has markedly improved, and their Spanish accents have eased ever so slightly.
Yesterday, we were working with the second conditional. An example of this, for those of you who don’t spend most of the week either planning or teaching ESL lessons, would be: If I were you, I wouldn’t touch that burning hot stove.
Student A, Cristina, had to ask Student B, Laura, the question, “If you could be a member of the opposite sex for one day, what would you do?”
Laura looked confused, and as I opened my mouth to try to help her along, she looked at me and asked, “But, what can a boy do that we cannot do?”
She wasn’t stumped by the grammar. She had no issue understanding the question. The mental block resulted from her utter inability to think of something that a boy could do that she couldn’t.
After recovering from the week’s best moment in feminism, I of course replied, “Nothing. Well, they can pee standing up.”
