Only an aunt

She told us today about the twin grandmothers she sees with a stroller in her street in the afternoons - that the slight differences in hair length and shirt prints only serve to emphasise the identical cut and colour of their hair, the identical cut of their shirts and even their swaying way of walking, and she can see that their lives until this point have been led in completely different places (their differently printed shirts give this away), and how therefore it is a miracle that two otherwise very separate beings, through the strange workings out of luck and choice and geographical distance, can nevertheless come to this: one of them the grandmother, surely, and the other only an aunt.
