As people age, they grow and learn in many different ways. Some of them are more committed to issues than they were before, and others have recognized that not everything in the world can be categorized easily. They have learned there are shades of gray between their own layers of black and white, and they see that what they thought before might not be applicable in every situation. When it comes to dating, two people who were previously incompatible might find they have grown toward each other.
Going out on a date with someone unsuitable is often seen as a waste of time, but suitability changes as people discover the world around them. Two people who tried to form a relationship while they were still in school could have broken up over disagreements about social issues, and they vowed they would never date again. Two decades later they might find they are on the same side of the fence when it comes to many issues, so trying again could lead them to a fulfilling relationship that will last the rest of their lives.
There are many mishaps when people date for the first time, and some of them can cause people to move on without going on another date together. If they happen to meet at the local coffee shop years later, their memory of the disaster date might have lost its sting. If they were to go on a second date, both of them might find that there does not need to be a disaster to bring them together.
Dating is a difficult social duty for many, and it can often turn out to be a disaster for the couple. Those who decide they are uninterested in a second date with a particular person might find things changed years later, and they could be open to the possibilities that were not present in the past.
