Mike,
You don't sound the least bit weird to me.
People often think I'm overly negative just because I always see the flaws and the mistakes in things. Truth is, the very gift that sometimes causes others to think I'm being negative also blesses me with the insight to see how those same things can be fixed and improved upon. As a result, I'm usually the first person people come to to get something fixed (though that can be a bit of a curse as well, since I'm the only person in my family that can fix almost anything).
If you ever walked into my shop without my knowing, you would likely find me openly debating two or three different points of view on some subject or other. I tend to have some of the best debates with nobody other than myself. When people ask who I'm talking to, I always tell them "me, myself, and I" -- and it is quite true!
As if that doesn't seem odd enough to others, I also have an almost compulsive need for certain textures, for only those certain textures can quiet my mind. My mind is pretty much a cacophony of competing thoughts, ideas, and trains of thoughts. I don't like malls or noisy restaurants (just too much chaos to process at once). I am also the last human being on Earth you would ever want to get directions from -- when I was younger I actually got lost on my family's property. Yes it was a large 'backyard' but I have zero inate sense of direction, so if I forget which direction I was headed (i.e. stop to look at something), I can't reorient myself. I can only drive rigid routes and get very lost if I have to stray from them terribly much.
And as if all that didn't make me weird enough, throw in my chronic illness, fibromaylgia, with intense pain and very limited endurance and all that goes with it. According to a recent study I should be loosing gray (brain) matter at about 10-11 times that normal rate, so by the math I have the brain of a 240+ year old man! No wonder why I have zero short term memory and always seem to be forgetting everything!
So, no Mike, you don't seem the least bit odd to me!
