People in Singapore get frequent reminders to be courteous in their daily lives, including when they take public transport and when they are at the cinema or eating at hawker centres.
But reminders on basic etiquette on the use of parks and park connectors are less common.
Among them is the riding of bicycles in underpasses. I have seen this happen on numerous occasions - it can be a danger to pedestrians who are walking in the close spaces of narrow underpasses.
I have also noticed an increasing number of park-goers who do not keep to their left when walking on footpaths, thereby obstructing the way of other park-goers and runners.
Information on what one should or should not do is available on the National Parks Board's website.
However, I am not sure how many residents actually take the trouble to familiarise themselves with the best practices of social behaviour.
Our behaviour and actions reflect the civic-mindedness and graciousness of our society, and we need to lead by example.
Perhaps it is time for each constituency to start refresher programmes that remind residents of these best practices and rules of etiquette.
