Once upon a time, there was a little girl named Dilruba who was 7 years old. Dilruba loved chocolates more than anything in the world! Every time she went to the market with her dad, she would ask him, 'Daddy, can you please buy me some chocolates?' Sometimes her dad would say yes and buy her a little bar of chocolate, but sometimes he would say no and tell her that eating too much chocolate is not good for her teeth.

But Dilruba loved chocolates so much, she couldn't resist them! One day, when her dad went to the market without her, he decided to buy a big bag of chocolates as a surprise for Dilruba. He thought, 'Maybe if Dilruba has lots of chocolates at once, she will understand why I don't buy them every time.'

When Dilruba's dad came back home, he called Dilruba into the kitchen where he had a big surprise waiting for her. 'Wow!' Dilruba exclaimed as she saw the bag of chocolates. 'Daddy, you're the best!' She started eating the chocolates one by one, munching on them happily.

But as Dilruba kept eating the chocolates, something started to feel not quite right. Her teeth started to ache, and she could feel some cavities forming. 'Ouch!' Dilruba cried out in pain. She realized that her dad was right all along. Eating too much chocolate had harmed her teeth.

Dilruba's dad felt sorry for her and hugged her tightly. He said, 'I'm sorry for not buying you chocolates all the time, but I want to keep your teeth healthy and strong. From now on, we'll only have chocolates once in a while, as a special treat.' Dilruba nodded and promised herself to take care of her teeth.
