What does someone mean like they’re not as nice as people think?

One of the teachers I worked with said, “Oh I’m not nice. I’m not as nice as people think and neither is my parents and brothers.”
I don’t get it, she is sweet, loving, kind and funny but why would she say she isn’t nice?
She is honest, even though she can be blunt and say what she thinks, even if it offended people.
