What will you do if you see your inlaws cheating your brother/sister?

To that time i wont react....since the relation ships are fragile.....we need to handle it carefully....Depending on the thing they did....I will react...I will try to discuss the issue with brother/sister-in-law without informing it to my daughter/son... WIth god blessings if it resolves then thats well and good....if notice that the same thing happend again.... then i will discuss the issue by sitting with the entire family members and try to resolve it...

i think at that instant i won't talk to either but will hint my brother after the incident has taken place and tell him to becareful in dealing with them. i will also let my partner know of what has expired between my brother and her parents or sister/brother. and be sure they will get to hear it. direct confrontation may result in a dispute and that will be very bad on both families.

yes, i will tell my wife and the matter will trashed out and the person in question is to be ejected from the house it will be done with immediate effect.
