Rohit was treating her like a joke and she definitely does not deserve this treatment.Jasleen has never said anything bad about anyone except for Dipika and that too even she has said whatever she feels about Dipika infornt of her face, Dipika is aware of what Jasleen thinks about her.
Rohit was speaking very sarcastically and hats off to Jasleen who kept going and did not stop the task as it was a very awkward situation to be ion plus Rohit made it more uncomfortable for her by making fun of what she is saying.
Jasleen definitely was saying how she is good at doing household chores, but the way Rohit was laughing whenever Jasleen was talking sounded like how he is not paying attention to her and how her words are not that important.
Juts because Jasleen is different from other people and she does not really think calculatedly before saying something, does not mean that,people need to make fun of her, but I guess sangat ka sar hota hai as Rohit is hanging out with the negativity ki dukaan Sriushty.
