Is there a rule in New York City saying that former teachers cannot be friends with former students?

I know they cannot be friends with students on facebook, but what about former students, especially when the teachers are no longer teachers.

Once you are an adult, you can be friends with whomever you want. And if the teacher isn't a teacher anymore, who is going to tell them who they can be on Facebook with? There aren't laws about these things, you know- just school policies.
