He's arrogant because he knows he's naturaly better at using the force than everyone. I'm willing to bet many of the training excercises Obi-Wan had him do, he did both faster than Obi-Wan would have, or expected. Besides, if he finds out that he is a direct child of the force, I think his ego would skyrocket.
Anakin is like a sponge ; he absorbs everything and anything with ease. Obi-1 schools Anakin as per the modus operandi of the Jedi Master to which Anakin wants him to put into 1st gear but Ben wants it to real slow teaching.
Anakin knows that his potential exceeds by far that of other padwans but he must be taught slowly and steadily as to not differentiate him nor discriminate the other Jedi.
Besides i would suppose that as Anakin tells his tale of his origin to the Jedi Academy (other padwans in training) they would start to pass comments on his unknown past , and make fun of Qui-gon's 'perhaps he is the chosen one' theory
because thats the way the cookie crumbles......
some people like to lead and others like to follow and attach themselves. items already posted are forgotten or no adequatly searched for so there is a new thread opened here....
if i am at work and some new guy asks me something i just give 'em a straight answer..........im not expecting him to go through the memos and find out himself .
now Nick over here knows that there is a search option; all he needs is some time to get used to it . Right ?
Could we cut the snide side chatter out please?
The answer is, aside from the obvious (i.e. he is very powerful), Anakin also wants to be a do-gooder, to put the Galaxy to rights, and so he sees fault everywhere and feels he has the power to change it. He believes others are holding him back from that.
There.
