"Is this how you fight in front of the children?" Lakshmi asked both of them. "I thought Karan was your favorite, grandmother."

"He used to be and he still is" She answered, supporting her hand with her chin.

"So what happened?" 

"He married her no matter how hard I try to make him understand that she is not the type of girl he should marry" Grandmother finally spill the beans. She was holding it in, ever since Priyanka came to the house. "I don't like this girl and he knows that too well."

"Is that it grandmother?" Karan asked. He was surprised that she was still holding to that. "Now, I understand why you are behaving this way."

Lakshmi tried her best time keep the peace but it was impossible now that grandmother had told the truth.
