premise: Last week 4 co - workers carpooled to a meeting which was about 1/2 hour drive away . All was fine , I was driving my 4 door car , it was a super nice day , we had the windows & sunroof open , the radio on for background music , and we had some conversation . After being in the car for less than 5 minutes , one female co - worker had to make a cell phone call that will be ' just a minute ' . What happened during the carpool   ride with your co - workers ?
hypothesis: We listened to some music and exchanged pleasantries .
