you are totally wrong! both are wives of two bros!
Thanks for asking this question. No X wasn’t being stupid or immature, infact, any problems, minor or major, she always used to talk directly to Y, but Y, on the other hand everytime used to complain for stupid things to X’s husband, that is why, this time X had to do it and complain to Y’s husband, because Y’s husband always used to think that my wife is always right and X is always wrong (just because X never discussed issues with Y’s husband and he never came to know ke unki wife kiya gull khilati hain)!!
