Keeping up with the Kardashians

Keeping up with the Kardashians- current episode. My assignment for this week is to watch a television episode, leaving the volume off and then turning it off to see if I was able to tell what it was about by looking at the body language. 
When watching the episode with no volume I saw Kim and Scott, running around a table with dolls, from seeing the background, it was obvious that they were in a CPR class, however it didn't look like either one of them were taking the class serious. The body language that I observed was two people feeling comfortable with each other, having a great time, possibly even making a fun time out of a situation that would be boring.
After putting on the volume, I was correct they were taking a CPR class, the instructor let them have a fun time for a short period and then they were required to get involved in the conversation that was taking place, he gave them examples, and finished conducting the class. 
This was a good example for me not to be judgemental, when I first reviewed the segment of the episode with out the volume I thought there was gooffiness, that both Scott and Kim were not taking the class seriously. However they had a bit of fun with actually taking the class. After I watched the segment again I saw that the instructor actually was making the class fun. I can see how things can be MISTAKEN, if not being heard.
