As Kathleen Kelly questioned in my all-time favorite, You've Got Mail, "What does that mean anyway? 'It's not personal, it's business?' Because it was personal to me."
I was recently demoted. After my boss strongly encouraged me to step down from my position she said, "Sarah, it's not personal." I responded, "I know...it's business." I wonder if she picked up the reference.
I consider myself humbled.
