So many to choose from, guess I'm lucky.

One that stands out in my memory is as a young person sitting on a train and someone throwing a brick through the window just above my head. After the shock of the 'near miss' plus having glass in my hair I was suffering from shock.

I still remember the woman, a fellow passenger, who calmly took her brush from her bag and gently brushed the glass from my hair, she was so kind and motherly towards this young stranger. Within a few minutes I had experienced the worst and best of human nature.
