When I was in school, my English teacher told me that a short story's beginning should mirror its ending, or at least the conclusion should in some way parallel the starting point of the story; but I was never told why. Is this a well accepted rule of thumb or is this just one type of writing style? If it is generally advisable, then please tell me why.
More information: At the time I automatically rejected it as her style, but now I am older I willing to find out if she had a point. Sadly I cannot just go ask her, thus I came to ask here.
Here is a very short example. It is only to give an example of the concept, please do not critique, I know it is very rough.
'Babies cry' I groaned at my wife 'go back to sleep'.
'But,' she yawned 'I just thought our neighbour was childless'.
I gasped, we dashed out the house to peek over his fence.
'It is only a cat singing a midnight song,' I gritted my teeth 'what waste of an hour'.
But when we returned to our house, guess who needed a lullaby.
