Thanks for sharing this Pia. It's a solid piece of writing. It clearly and honestly expresses your feelings and opinion. It's also helpful to me as I am a textbook introvert as well. I understand the "enough to think about things inside my head". Introverts gain energy from solitude, extroverts draw it from crowds. Very different ways of being in the world. Thanks too for being willing to try social networks. They are valuable tools. If all you use them for is that, that's fine. I'm not asking you to weave them into the fabric of the rest of your world, nor do you need to.
