When I was a kid at an all-girls' junior school, I (being the poorest but brightest) was the alpha female in a group of friends that included a pair of twins. One day one of the twins was called in to see the headmistress, and when she came back she was crying. The only one of us she would talk to was me, so we went off to a corner of the playground and she told me her sister had been rushed to hospital. Like an idiot, I just stood there looking horror-stricken and said: "Oh no, that's awful!" I was no help at all. But another girl in our group had an elder sister who, tragically, was dying of leukaemia. She comforted the twin and was brilliant at it. That scene haunts me to this day, but it certainly opened my eyes about how to comfort someone. (The other twin was fine, by the way!)
