Interestingly, when I was far and away better than everyone else academically with the school subjects, I WAS asked for help, etc... but never really went farther than providing help, etc....
Still, if you think bullies, etc... care if you are smart, etc, you're wrong. In fact, if you make it too obvious, they feel insulted, etc... and get angrier. The only reason I can really come up with for people attacking me is that they thought I was an easy mark, and thought it made them look big. You would THINK it would be just the opposite, that beating me up would be met with "SO WHAT?" and, if they were beaten up by me, they would be met with disdainful surprise! I always tried to speak at the level of my audience. I had some interests that everyone knew about, but I never flaunted them, etc...
