|A man walks past a beggar every day and gives him Rs. 100 and that continues for a year. Suddenly the daily donation changes to Rs. 75.|
"Well," the beggar thinks, "it's still better than nothing."
A year passes in this way until the man's daily donation suddenly becomes Rs. 50.
"What's going on now?" the beggar asks his donor. "First you give me Rs. 100 every day, then Rs. 75 and now only Rs. 50. What's the problem?"
"Well," the man says, "last year my eldest son went to university. It's very expensive, so I had to cut costs. This year my daughter also went to university, so I had to cut my expenses even further."
"And how many children do you have?" the beggar asks.
"Four," the man replies.
"Well," says the beggar, "I hope you don't plan to educate them all at my expense."
