In other words, you speak the mainstream language recognized by Muggles.
• Resilience of a rubber band:You don't snap when stretched to your limits by panicked, frustrated and/or irate users who have run into dead ends, chalk it up to "it's a networking issue" and are operating on their last nerve. You have the temperament of a Zen monk on a Rocky Mountain high. You enjoy sharing knowledge, working towards a solution, and do so in a way that's respectful and understanding.
• Appetite for learning: You're always reaching for the next apple on the knowledge tree, as well as the last piece of pizza in the box.
