I Have a Question

I think a circle person is someone you added but hasn't added you as a friend yet - someone you're following.

Friends both are following.
Follower is someone following you but you didn't add as a friend.

Thank you all, I get it now, obvious when you think about it 😃😃😃

MrBeardTastic is correct. I have also added this to the unofficial FAQ now. Thanks for asking!
