Paki bhai, no we are not mad 
at your other thread. These are discussions and it’s good to hear different perspectives.
Regarding in laws, I was told that taking care of them earns you extra credit but if you don’t, you do not get gunnah. There is no obligation to serve your in laws.
However, I feel that as a wife, it is my priority to keep my husband happy (yeah feminists, bash me I don’t care, but it is), and if taking care of my husband’s family makes him happy I will do it by all means. Also, it is unnecessary to alienate yourself from his family… why the need? Your kids need the love and affection of dadi and dada. Also, if I want my parents to be respected and taken care of, I must also demonstrate similar actions toward my in laws. It’s not that hard.
