My best friend as a child lived like 4 houses down the cul de sac from us, and I was literally at his house every day.
But still, every day I'd knock and ask if he could play, despite his parents telling me over and over that I could just come inside whenever I wanted.
Yup. It’s a developmental disorder instead of a mental illness (like autism). Our frontal lobe or prefrontal cortex didn’t develop properly.
I think ADHD is a horrible name for it. Executive Functioning Disorder is a much more accurate name.
