If you are required to say hello to someone when you see them, you are on a hello program with them.

The hello list is comprised of all the individual people with whom you are on a hello program.
Girl: Hello

Guy: Hello

Girl's friend: Why the fuck did you say hello to that guy?

Girl: Gaa, he bought my textbook. Now we're on an eternal hello program.
