Gervais became an atheist at the age of eight when Bob, his older brother by 11 years, asked him why he believed in God. "My mother went 'Bob!' and that was it. I knew she was hiding something and he was telling the truth. My tool to understanding throughout my life has been non-verbal communication, observing the minutia of human behaviour. It's in my acting and my writing and that was where it began."
His mum's word vs my mum's, I guess.
