Teaching is Hard!!

Today, I spent the day as a volunteer teacher in a local school. Since the students were well behaved, I had a good time. Nevertheless, I am exhausted for the following reasons:

1. I spent the entire day on my feet and moving around the room;
   
2. Keeping 20 kids involved in the lessons for an entire day was difficult and mentally taxing.
   
3. Our curriculum was provided by a third-party. Nevertheless, I spent 2 hours preparing for the class.
   
4. I do not have any papers to grade tonight. My wife, who is a real teacher, does. Furthermore, she has to prepare her own curriculum.
   

I love my wife and know she works hard. By spending the day in her shoes, I feel her pain.
