O.I.B.B.
O. I. B. B. means you’re so invisible, the only way people know who you are is if you’re in the yearbook. You’re like a shadow that no one saw.
My old rival is in the yearbook. Now I know why no one ever saw him.
I found my old friend’s grandma in the yearbook. Now I know why no one remembered her.
My brother is in the yearbook. Now I know why no one ever noticed him.
