Should I unfriend my teacher on Facebook?

[Fanaticalkiss350]

Hi.
So, I go to this small Christian private school. I won't be there next year due to money issues and moving into a new house. However, friending teachers was in a way, required to have a better connection. The website says I should have friended teachers.
Should In unfriend my teachers when I go to my new school? They won't be my new teachers and I'm afraid to post anything without getting yelled back. Thanks.

Your FB is private and belongs to you. Only you decide what to share and with whom. I would personally have no busy bodies on FB.
