For many people, dating is about finding common ground. Going out with someone means getting to know their likes and dislikes. It also gives people a chance to look at life through another person's eyes. Sometimes these people see things they like and continue dating. Other times, it just doesn’t work out. If one person does not fly because they don’t care for heights, they might find themselves dating a sky diver. If it matters to neither of them that one flies and one doesn’t, they might find a future together. Of course the non-flyer might also be willing to explore a future where they will dare to try sky diving.
