What are you talking about as you drive with a passenger in your car or truck?

as i drive, i tend to look over into other cars or trucks or SUVs and see people laughing or talking or not saying anything. you can tell so much about “people” just taking that quick glance as you drive. what are you talking and laughing about? why are you not saying a word?

if you are by yourself, who is on the cell phone with you? are you arguing? are you planning an event as you drive the open road? why does your conversation on the cell phone need to be held right now? is it a distraction?
