Platypus, thanks so much, you've done a an awesome job saying things I was thinking but couldn't figure out how to express. I know exactly what you mean about 'strict' being a euphemism for yelling and see a teacher like that in my son's Kindergarten group. This year my son has a teacher that's just like you'd described as far as being warm but not following through and I think he's just not mature enough to handle that much freedom yet.
Your last paragraph describes my son very well... a lot to think about on the ADHD side of things still for sure. Thank you so much again!!
