A letter. For me. That was something of an event. The crisp-cornered envelope, puffed up with its thickly folded contents, was addressed in a hand that must have given the postman a certain amount of trouble. Although the style of the writing was old-fashioned, with its heavily embellished capitals and curly flourishes, my first impression was that it had been written by a child. The letters seemed untrained. Their uneven strokes either faded into nothing or were heavily etched into the paper. There was no sense of flow in the letters that spelled out my name. Each had been undertaken separately — M A R G A R E T L E A — as a new and daunting enterprise. But I knew no children. That is when I thought, It is the hand of an invalid.
