I usually don't laugh at students - but this was hilarious

Today in my literature class we started The Scarlet Letter. It is always interesting to introduce the book that deals with guilt, secret sin, forgiveness, and love. I haven't taught the book for three years, and I have never taught the book in a non-Christian setting.

It was an interesting first day. I think I gave some of my students mini heart attacks when I told them to write down their deepest, darkest secret and I pulled one out to read. Shook my head and said, "That's interesting." I later told them that it was a blank one I had planted, but they were sufficiently freaked and only started breathing easier when the papers were in the trash and I threw papers that I had been amassing over the last few weeks on top.

As part of the book, we needed to talk about the definition of adultery and what is considered adultery. One of my students is a little bit airy sometimes, no joke, today he raised his hand and when I called on him, he said, "Wait, I am still processing my question." The boy cracks me up.
But that wasn't what he said that had me laughing for the rest of the day.

Forgive me, because I am not going to tell this perfectly, and you will not find it nearly as funny as I did, but I had just told the students that the Puritan belief was that you couldn't have sex with anyone other than your spouse. He raises his hand and says, "What if you were married?"

I replied, "Do you mean could you have sex when you're married? Head nod yes as a response. "Because, yeah you can," I answer as I and the whole class have burst out laughing. (Whatever was the actual question, he made it seem like he was asking if it was okay to have sex when you are married.)

He realized his mistake (and probably that his married parents had to have sex for him to be here) and said, "No, I didn't mean that."

"Did you mean is it adultery if a married person has sex with someone besides their spouse?" Head nod yes. "According to Puritan belief, if you had sex with anyone other than your spouse, it was wrong."

"Oh, that's what I thought."

I went on to the next activity and told him, "I know what you were meaning to ask, but I will be laughing the rest of the day about that."
