Whenever people are first starting to date they instinctively present their best, brightest, happiest face to the other party. I don’t think that people make this choice on purpose… I don’t believe that anyone goes out of their way to try to deceive the other party unless they are a sociopath. However, I think that it’s human nature to be on your best behavior when you are encountering a new social contact. This is especially the case if you find the other party to be attractive. That’s why, I recommend anyone who is newly in a relationship takes a road trip together. If you really want to know someone, put pressure on them. So many things can go wrong on a road trip, especially with the temperature. If you are on a long car ride it immediately requires you to compromise on the indoor air quality. You’ll find out right away if you have compatible thoughts about the air temperature and air quality. If one of you is constantly turning up the air-conditioning system while the other one shivers in silence, it’s not a great sign for your relationship down the road. If one person demands that the heating system is running while the other human complains about sweating, you’re going to have some compromises to make. Most significantly, if the central heating and cooling equipment breaks down during your road trip, you’ll find out about the temperature of their temperaments very quickly. If someone gets a hot head or starts boiling over, you might want to consider how they’re going to react to hot and cold situations down the road.
