Eye contact is a serious issue for me, I can't look anyone in the face.
I also have obsessive interests about which my knowledge is nearly encyclopedic. It's not normal to be able name every car sold in this country for the last fifteen years, along with all of the trim levels and powertrain options.
It takes a conscious effort not to ramble on about my obsession. I can usually manage, but God help you if you bring the topic up.
Extreme levels of stress when my routine/plans are disturbed. I have a very hard time "going with the flow." Panic attacks are common.
Very poor "fine motor control." At least this is what my folks were told. I had to take special ed PE as a kid, and I'm still crazy clumsy to this day. My handwriting is entirely illegible, even to me. And do not hand me anything fragile, like a vase or a baby.
I sometimes go non-verbal when I'm especially stressed. This was very frequent when I was a kid. It has gotten better as I've gotten older, though it still happens occasionally. I'll try to speak, and find that I just can't.
I have some sensory issues. Bright lights, loud noises. Granted, most people don't like those things, but they seem to be able to tolerate them much better than I can. And touch is a biggie. If you touch me, and I don't see it coming, I will jump, and I will shout. I can't help it. Even when I do see it coming, it's all I can do not to jerk away.

well I'd just rather never ever even see beauty again.
Well as life gets longer, awful feels softer.
And it feels pretty soft to me.
