You are logical. Though you are quiet and don't usually make yourself noticed, you are a person of great knowledge and 'know-how.' Having the trait of thinking before speaking coupled with the ability to acknowledge endless possibilities makes you seem like a genius in a debate or friendly conversation. But being so enlightened makes you seem arrogant to some people, a 'know-it-all' who sees themself higher than others. You are also impatient with people who don't catch on quickly to theories or technical works as quickly as you wish, and soon cut off lines with them, leaving them confused and hurt. Being more patient and thoughtful with other people will surely be a benefit to you. While you have your own theories and knowledge, there are others just as interesting and curious like you who are willing to have a friendly chat and/or debate with you if you opened up.
