They say it's in bad form to start off with the weather. But let's talk about the weather, form be damned.
Is the mood determined by the weather? Yes, I hear you say. But maybe, in some ways, your mood manifests as the colour of the weather this evening, more so when you refrain from employing spoken words to express, which is what you really should do, they say.
But then, they say a lot of things, don't they.
There is a storm outside my window. That should tell you enough. It has been raining very heavily. I can hear thunder and see the lightning light up these words I am typing.
Yes, sometimes mood and untimely weather are too similar for comfort. Neither shall bode well in the long run.
