What if I am in the car with two other people arguing?

There are many things for you to evaluate before decide to do anything about this situation.

First, examine the argument. Is it something private that is discussed using very vague terms and nudging? If this is the case, it would be best to just try your best to tune them out and look out the window, because chances are they are talking about you. Along with looking out the window, you can do a self-presentation checklist, which covers your body odor, breath, hair, clothing and much much more.

If you are relatively sure the argument is not about you, and you'd like to make things less awkward for yourself, you can always pick a side. Nothing gets everyone involved like a good ol' debate with friends. Who knows, you might actually be the deciding factor in your friend winning the argument. It is important to note that you do not have to be learned about the subject at hand in order to participate. Blind faith can be considered a perk if such a situation occurs.

If you want to make things less awkward, but also want people to stop fighting, you can always try to change the situation. Here is the conversation, verbatim, that I had in a car amongst two fighting parties. Notice how I expertly weave myself in to save us all:

Woman: Why do you always call him my baby. He's your's, too.

Man: How do you even know? You were to strung out to know who's who.

Me: Cold today!

Did you feel the magic happen? I know I did. All previous talking points and fraternity issues were forgotten as everyone instantly remembered it was a bit chilly outside. We ended up talking joyfully for the rest of the car ride, singing to music on the radio, and not talking about who's your baby's daddy.

However, you must remember that all arguments are better when you interrupt when the iron is lukewarm. DO NOT LET THE AWKWARD SILENCE SET IN. I cannot stress this enough. This is the point of no return and ensures that awkward shifting in silence will happen for the next 20 minutes. If it means just bailing out of the car to stop argument, so be it. The stop sign you are wrapped around will be a fun conversation topic that will distract the arguers for trips to come.
