For once, I want to give Anupama this benefit. Let us say that her two children became these horrible because they had the influence of Baa and Vanraj. And yes, it happens in real life as well that no matter how hard parents try, some children grow up as pathetic children. In her case, she was all alone on top of that. Her husband wasn't supporting her.
But just imagine CA's environment. She is surrounded by ek se barkar ek, Barkha, Malti Devi, Pakhi and the other Shahs. She will obviously become worse than Pakhi. She is literally living with gundas and gundis.
So, Anuj and Anupama should give away the house to Malti Devi and live away from them. CA needs Mukku and GK kaka.
