I really don't understand where you're getting your information from. According to most other people on this site, and in my own experience, beardies generally have a good temper, and are very friendly. Only when something is done wrong, or they are mistreated or sick, do they behave in such a manner. I'll admit, there may be the rare beardie that just generally has issues with people, but they don't behave that way just for fun.
