Finding Humor In A Strange Situation

I am a person that can laugh in really awkward situations and always find humor in something so I won't show my real emotions. Like a couple weeks ago me and my friends went to Statesboro to go out one night, and there was a lot of tension in my car. My car seats a maximum of 5 people, but that night I had a total of 7. This is where some of the tension came from, because my friend and her boyfriend were arguing because he did not want her to ride with her other friends so she rode with me and sense my car was full she had to sit on his lap and that made everything 10x worse because they were both pissed off at each other and arguing for 20 minutes about the situation. In the meantime I just thought it was hilarious that she had to sit on his lap the whole 2 hrs back and they were arguing.
