Welcome to my world of dyslexia... :)
Wow, this story is my hope for humanity! Keep it up and keep doing what you do, Mathed-potatoes! :)
People never cease to amaze me in every way.
Today, we had an emergency response drill. This involves flashing lights and loud sounds. I have a neurological disorder that makes this type of even very uncomfortable.
The hour before this drill, I had an incredibly disappointing interaction with one of my work supervisors. My reaction was much stronger than I might have anticipated on a theoretical level, and I was still reeling when the drill started… so I didn’t take steps to avoid the sensory barrage. The loud noises happen first, and I was already starting to spiral the drain.
And then…
And then one of my students caught my attention. She told me the lights were about to start flashing, and asked if I needed to go outside. I was so far gone I couldn’t really process how to do the ‘get outside’ thing. Like, I couldn’t find ‘outside.’ So she sherpa’d me to safety, just in time to avoid the flashy lights that would have triggered a full meltdown.
So, here’s the thing: I have mentioned my disorder to her once, in passing, by name only. She literally remembered that I had a condition, and took steps to know what emergency protocol I might need in certain situations. I thanked her profusely, and asked how she had learned to be so sensitive to stuff like that. She told me she has a younger sister with a disability, and so she understands how significant the timely attention of a knowledgeable ally can be.
It is significant. It makes a world of difference.
She saved the day for me.
She kept me from having to leave in the middle of the day, from having to cancel my afternoon discussions.
And, at that particular moment, when I was still shocked by an instance of the human capacity to harm, she reminded that their capacity to help, to be compassionate, to care about one another, is far greater still.
Beautiful, where can I get my hands on one of these? :)
If you take each of the 4 sides of a square and modify the angle of the dragon fractal as you go up, you get this shape. I’m still fighting the 3d models to get a nice smooth version.
Finally Vihart post a video again!
This slide is really something! :)
