One word... Survival.
Be it as a kid at school "acting" tough to stay in with the crowd so he isn't the one picked on, or be it in the Courts, as a job, to win, to survive in the practice, the bottom line is all human beings have emotions and can break at any time.
Speaking of the "in crowd at school", my emotions personally went quiet for a few days recently... I found my old school class, there was a boy, blonde, and in the recent photos, main shot, dark haired... I remembered the name and I remembered an accident, to be honest, I thought he was dead..
From little tid bits of conversation as I was wary not to push for answers I wanted, as that's un-fair, I gleened that he tried to be with "tough boys" at school, only to end up down the bottom of a cliff, from the age of 10, not remembering why he was a paraplegic, until much later in life, when he recalled what really happened, two boys, laughing and pushing him over...
Tough kids acting tough.... And a fully grown man who has never lived his life past 10 years of age, that has written a book in word, over the past 38 years once he started to remember...
Those "tuff guys" I hope every day of their lives remembered what they did and that it wasn't tuff at all..
Off topic sorry David:)
