"No Punishment, Please"

Today was like any other day, I prepared my lesson plans and at 4:30 my tutorial arrived. But today, instead of teaching my second class (consisting of two students; 20yr guy/18yr girl) I ended up dismissing early. Why? Well to my surprise, not everyone was in the right mind.

Things started off strange when my male student was not there on time. Both my students are usually very punctional, but today was different. When he finally arrived on his motorbike, I went out to greet him. I waved to him and gestured for him to come inside. A couple minutes later, he stumbled him. The first thing he says to me is, "no punishment, please." I thought he was talking about him being late. That was not was he was referring to. He begins speaking to his classmate in thai, and she informs me that he had drunk acohcol before coming to school. His giggly nature (usually very quiet and shy) made it evident that he was impaired. I was shocked. I did not know how to react. Since I have two students studying in this class, I hesitated to move on with the lesson plan. I would have to reteach everything to him the next day, so I opted to dismiss and resume class the following day. I tried to make it clear to him and told him never to come to class after drinking. I couldn't believe what I had just experienced, I was totally out of my element. On top of that, I was worried about him driving. I tried to tell him, he shouldn't be driving; but he just giggled, and kept saying "sorry." This experience made for an interesting class, but I hope it never happens again.
