I'm not even sure this behavior is gifted specific.
I really think gifted kids (at least mine) are more "difficult" than ND in that they want to boss everyone around (from very young age--ask my 6 yr old), think they know more than others (sometimes they do!), are frustrated or impatient, don't want to go through the courtesy/polite behavior as much as accomplish their goals. It is definitely harder to deal with HG kids--ask any teacher who has had them. They are not naturally compliant (in general).
