my mother in law does not know how to mind her business , i do n't understand why she has to be so undermining to us . what a jerk ! why is she always in your biz ? i do n't think she has any idea how nosy and irritating she is . she continually will tell our girls how their father and i are doing things wrong . i would get up in her face and show her who 's boss . break out the broom and crack it across her old , measly back !
The mother-in-law's constant interference, undermining behavior, and criticism of the person's parenting.
