It will be a Tuesday: When that will be I cannot say.
Or it might be a Thursday.
It will be an ordinary day until 11am. Then he (or she) will be unable to sit at his (or her) desk and will find himself or herself walking towards the open air.
When he (or she) gets to the street he (or she) will be surprised to find lots of people standing in the street, on the pavements, in the road, looking like he (or she) is looking – at the buildings and then at each other.
He (or she) knew he could not continue with things the way they were. Now he (or she) wonders whether there is anyone who has a clue as to what to do next.
He (or she) is trembling and happy. Today is different.
