I've been extroverted for most of my life, but since not working full-time, I am quite introverted and have time to read to my heart's content. I've encountered the concerned look and the questions, 'Have you gone out this week?' I find I need the energy of other people, but not too much or they exhaust me. Some people become uncomfortable when you are different, don't they? But are they worried it's they who are different?
