Why did Babu in his father go to Nagendra twice ?

In the story "The Heavenly Parasol," Babu went to Nagendra twice for two main reasons:

1. To seek help and advice: The first time Babu visited Nagendra, he was seeking guidance and support from his father. He likely went to discuss his problems or concerns and to get his father's wisdom.
2. To fulfill a promise or obligation: The second visit might have been to fulfill a promise he made to his father, or perhaps to report back on something, or to undertake a task that Nagendra had assigned him. The specific reason for the second visit would depend on the plot developments in the story.
