One day, a colleague, Sarah, who was relatively new to the ESL teaching field, told me about two grammar questions that one of her students had presented to her. (*If you are curious, you can see the questions and my explanation at the end of this posting.) She said that after class, she had spent quite a bit of time searching for answers on the internet but to no avail. Finally, she decided to ask me.

It turned out to be a fun interaction and a kind of puzzle for me to solve. On my drive home after classes that day, I realized that I was feeling great, but I didn’t think that there was any specific reason for it. A while later, I happened to come across some research that perhaps explained my exuberant emotion. And it had nothing to do with it being a Friday.
