I am very shy when talking, put me in a online forum or chat or something and my shyness goes away. For me I have a hard time talking. Its like my head is going 90MPH and I end up leaving out parts that I have to go back and explain. Read an INTP topic and its notice how it goes all over the place. Thats my thought when it comes to expressing myself. When I write I will start several sections and just kinda bounce all over the place adding parts here and there. Its like I am putting together a puzzle.
