Pavements these days are not the safe havens they used to be. Did you see that horrifying incident on television recently
when heavy masonry collapsed from a shop roof, missing a pedestrian by inches? That person had a lucky escape.
Another incident involved a manhole cover exploding, making people near it scream and jump away.
We must also avoid using pavements battered by high winds when shop signs start rattling on their moorings, threatening to fly off and smash into passers-by. These incidents have also happened.
