Emma and Dexter meet on the night of their university graduation. We see them every year on the anniversary of that date - July 15th. Emma is smart but success doesn't come quickly for her, whereas for Dexter, success and women come very easily. Through the years they grow apart as their lives take different directions and they meet other people. But as they grow apart from those other people and their lives start taking opposite directions again, Emma and Dexter find that they belong with each other.—napierslogs
After spending the night together on the night of their college graduation Dexter and Emma are shown each year on the same date to see where they are in their lives. They are sometimes together, sometimes not, on that day.
