why will she come to your house when you have cought her doing “chori”. you mean she is a thief??? taking something from her matrimonial home cannot be said chori. she is also one of the member of your family and not outsider. she is married to your brother. if she is not coming to your house. you people make a courtesy visit to her house with a small gifts+or sweets. see the difference. try to have good relation with her and she will treat you and your family with same. if you think more of what you can do rather than what others can do . we can avoid most of the problems and live happily.
