Pretty good and not particularly bullish. What's your point?
I don't think "enjoyment" of the fact that you just asserted/defended yourself does any harm. Holding a grudge is far worse, imho. I recall some guy from the ScienceBlogs commenting on his high school reunion, and you could tell he had some deep running hatred going on even after several years - to the point of enrolling his kids in martial arts classes with a "so-maybe-they-can-get-some-sweet-revenge-for-me" type of attitude.
The martial arts are not bad per se, but a parent teaching a kid that it's ok to turn to violence when they can't get along with their peers is not very responsible.
FWIW, the other day I read about a research (and this matches my personal anedoctes) that younger brothers (i.e. the ones who usually get bullied by the older brothers) tend to show more empathy towards other people than older ones.
In contrast, psychopaths almost always have a history of being a victim of child abuse by family members. So, in my mind, values coming from the authority figures in a family are really on a whole different level than simply having maturity.
>> enjoy having defended yourself
Uh. I think the term we should be using here is "relief".
