Oh Janey, I forgot about some of this until you mentioned it. People who are talkers, just exhaust me. I mean as in total exhaustion. I cannot wait to get away from them. I prefer peace and quiet most of the time. There is way too much noise in the world.
I too have the pillow/sheet thing. I have the hardest time sleeping anywhere but on my sheets with my pillow. The sheets are just too scratchy. When I go away, which I just did, I take my pillow and comforter, and my fan for white noise. I envy people who can just lay their head anywhere and sleep. I just can't do it.
I have always felt like I did not fit in. I too notice much that others do not. I am very intuitive and hypersensitive to people. I have been known to never seek out a person again, just based upon the first meeting.
