Sir — Our national flag is a symbol of the nation’s pride and respect. There is liberal use of the flag on Independence Day and Republic Day. There is a new trend of selling flags made of paper and plastic, which is incorrect. With a sense of national pride, people enthusiastically buy such flags but the very next day, we find them being trampled upon on roads and thrown into dustbins. By allowing this to happen, people forget that they are insulting the flag. Often, these flags are burnt along with the garbage. It is the duty of every individual to maintain respect towards the national flag.
