While me and RAH were going through our separation there was lot of blame, anger and hurt flying around. I recall typing to him something on the lines of:
"While we are at it, don't you think its time you grew up and started acting like a 45 year old man? You sound like a petulant teenager."
I knew at the time about the prefrontal cortex stuff so I wrote those words with more than a hint of irony but really - how true it is.
