How I came to know how to program the alarm

Read the post under this one first to understand. While the guy was installing the alarm system, I kept asking him questions. He gave me very basic answers because he was annoyed, I think. After I kept asking he gave me the same answer. Then dad said, "Dude, he won't stop until you actually tell him what he is asking". Then the next time I asked, he took like 2 minutes to explain it in depth to me. Then I stopped asking because he explained it perfectly. And now I can program and configure his alarm to his hearts content.
