Sleep is for the weak

Since the beginning of August I have been teaching a group of eleven chemical engineers on Monday, Wednesday, and Friday mornings. They are all around 30-40 years old, and are a lot of fun to teach. We have been preparing for the Test Of English for the International Community until now, but now we have a discussion book and we talk about news articles, so I imagine that the class will only become more interesting. Also, the grounds of the company are rather nice:

I am getting paid fairly well to teach the class, though I am only getting about a third of what the chemical engineering company pays my school, and basically all the school provides is the book. The only problem with the class is that it is from 7:30 to 8:20 in the morning, so I have been getting up with the sun half of the time for the last month and a half.
