Well,confident people, especially the overconfident ones take a stand and stick to it. They'd say anything and do anything to prove their point and would barely want to accept another's opinion, that's where the illusion of arrogant sets in the minds of those who have to deal with them.
For humility aspect, there are the humble people who are offended and would confront their offenders humbly, and there are those who'd chose to do nothing and just let it slide and fade away. The former are those that are more likely to be considered timid, because their decision not to act created the illusion in the minds of people that they can't act.
Can I then say , a timid person is humble. But a humble person is not timid ? @nigtroy
A timid personlooks humble but that's just because of the timidity, it's not genuine humility.
A humble person is not timid, but you can have the shy ones labeled by people as timid.
Oo this is clear.. and interesting .. I appreciate your selfless involvement and contribution
Thank you @nigtroy
