Re: Materal words of wisdom
I can give you an example from my sister’s life (well, she got the same advice from mom too 
). Her in-laws are generally okay, but they love to find faults with sis’s daughter. “She is too loud” “Too bold” “Spends too much time on the phone”. Now, my niece is one of the nicest teenagers I know, but she does get upset with these constant accusations and fault-finding (she is a teen after all!). It got really bad when the in-laws came to live with my sister during my niece’s final exams. My sister could see that her daughter was upset and angry all the time because her grandparents cut her no slack. One particular incident ended in my niece being in tears because the grandparents kept taunting her about waking up late (she had stayed up all night studying). That made my sister put her foot down - she firmly told her in laws to not disturb her daughter while she was studying and any complaint they had about their granddaughter should come to her (my sis) only. Plus she and my bro-in-law have agreed to not invite in-laws over during niece’s exams. This may seem rude to some, but her daughter’s mental well being was at stake, and her in-laws refused to behave like adults.
