And yes, nearly all teachers can recall at least one day each semester where they nearly lose it with one of these classes. Usually, it's nothing a stiff drink or a lot of prayer can't solve, but it's also usually the sign that it's the mid-term and it's time to take a vacation.
When these signs aren't apparent, an email from a student like this one might be the last glaring signal that you need a break.
I am very sorry for making you so depressed and let you almost lost your temper this afternoon. I consider I owe you an apology for my inactivity in your class.
I think that the awkward silent air in class can definitely make any oral English teacher mad at her students. Please calm down!, we are still your students. For myself, I wish I could speak English fluently. I wish I had ever had a good English teacher like you teaching me when I started learning English. And I wish I had been more active today.
So, please forgive us for our inactivity in your class this afternoon.
Boy, Michael. I knew I was a peeved at you, but I didn't realize that you were making me depressed! I especially like the pleading tone when he tells me to, "Please come down!" followed by a badly misplaced comma. It really is time for a vacation!
