Imagine driving along a highway. In the distance you see many tall buildings. Without warning, one of them is engulfed in smoke, then the smoke clears and you see the building falling to the ground.*
Later, you see the pile of rubble marking the spot the building occupied. A sign outside the perimeter announces a fine new complex for the arts to be erected on the site.
In people's lives they sometimes need to renovate or even rebuild completely. The sight of destruction and ruins in a person's life might seem sad. You cannot know what splendours might rise to take their place.
Try not to judge the quality of another's life on the basis of your external observations.
We should all wear signs: "Site Under Development".
*My editor's first reaction was that this was a prophesy of 9-11 back in the 1980s.
