For small children it is great fun game to see the snake raising its hood on the harping tunes. When encountered by people, the cobras usually try to escape from the scence. But occasionally defend them boldly and may appear aggressive and offensive. Most of these snakes elevate the head and spread the neck as a threat gesture to make the people run from them.
