Don't feel inferior! Your mapping ability is an amazing one to have, and very useful. I often wish some of my quirks had more practical application; as it is they can be somewhat isolating, because I don't often meet people who are willing or able to understand one of the best things in my life. Everyone can appreciate a great navigator, and being able to visualize everything from above is exceptional.
Ooh, the smooth-crinkly thing reminds me of something else... and I'm beginning to think that maybe a lot of us have a lot of very similar abilities or quirks, it's all just a matter of how aware of them we are, and what form they take. Minor details are all different.
But the crinkly thing... sometimes when I close my eyes, I suddenly visualize a landscape which is blanketed with graffiti... hyper-detailed, hyper-dense, hyper-messy graffiti. Every square foot is filled with chaos, like a Where's Waldo drawing of random markings and color. Random and yet not random, because graffiti has a pattern and a purpose even though it looks messy. Just super-complex. Some kind of visual metaphor perhaps for trying to decipher all the subtle significances and complexities of life.
Sciuridae, I can relate to that as well. I hated the word "moral" for a long time, purely for the sound of it and not the meaning. On the other hand, I remember a day in kindergarten where I laughed myself silly at the lunch table because the more I repeated the word "squares", the more ridiculous it sounded to me.
