48 years ago, a young woman gave her boyfriend a Christmas gift. But before he could open it, she broke up with him. He took the gift home and tossed it under the tree, vowing to never open it. He included the gift under the tree for the last 48 years and was finally enticed to open the present. He reached out to the woman who dumped him and she joined the unwrapping of the gift, forgetting what it was. 

The present was a book, titled Love Is by Kim Grove.
