I'm not sure if this one is uncommon or not, but I really REALLY dislike soap residue. Our dish washing soap does this, and putting dishes away is awful because of it. It makes my hands want to cry.
I don't like to have my toes touching, either. I'll let them fall together if I'm not thinking about it, but if I'm suddenly aware of it, I get really uncomfortable.
Also, anything that involves being able to feel my bones under my skin. Typing on a tablet, walking on anything that's not soft, grabbing my arm and feeling the arm bone, stuff like that. I'm a really scrawny person, so I run into some problems there.
One more-- I hate it when I'm around people eating fruits and vegetables. I can't even stand eating them myself, and watching them being eaten by others is pretty awful too, though not as bad. I hate the noises they make, and I hate seeing the seeds on their plate. Uuughhh.
