Bidaai lacks basic manners. They dont have any concept of locking the door or knocking at the door. In the earlier episodes Ragini entered Ranvir's room without knocking, the other day Gunni enters without knocking at the door. And when they are having a private moment in the bedroom y dont they close the door. That is normal in everyhousehold whether you are rich or poor. Every couple wants to have private moment somebody keeps itruding them. Even Ranvir use to enter Salekh's room without knocking, which atleast i never liked. Sadhana should teach Alekh that he needs to knock before he enters somebody's private room. And dont tell me that u cant teach Alekh as he learn and listen to other things very carefully.
