There's someone I know who appears to have NO SELF CONFIDENCE at all, but then, at certain times, they can have the courage to let you know that you upset them. Does that mean that they have no confidence?? What does it mean?
Even the way they let you know that you upset them isn't very assertive, its quite dismissive. (i.e. they just show you they are upset without standing their ground - if that makes sense).

So, under what circumstances or traits would you label someone as having no self-confidence?
