when we see red, we automatically have a response to it

This is why I never use red to offer corrections on my students' work. I typically use green or purple, depending on the type of feedback I'm giving.

Did any in the US notice over the last years I write in US English?

Of course mate! I knew you were Aussie, so assumed you learned British. But I was happy that you left off all the extra vowels. I think you had an article a while back where you touched on the difference between analog and analogue, as well as among and amongst. US wants no business with those extra letters, which dates back to being cheap (fucking capitalism) and wanting to make things easier with the old-school printing presses.

now in the divergent category, and have the brain scans to prove it.

Welcome to the club! I've seen a few psychotherapists, but it never really did much for me because they were all preoccupied with me smoking less weed. None of them ever gave me a clear diagnosis either, because they would tell me that my daily weed use was making it too hard to distinguish my "medicated" state from my natural state. Clowns!
