Some people are more emotionally fragile than others ... are devastated for weeks by a gang of teenagers shouting something at them. Others would just think 'Twats' and move on. Others would shout obscenities back, and fume for days ... and still others wouldn't even notice.
Why is this? What causes these huge gulfs between people's personalities? How can we raise our children to be resiliant? How can we become more resiliant ourselves?
