For background: my older Dsis is a teacher (or was because she's working in another field now) and is against private schools. She has worked in ONE private school for three years and is an expert (according to herself) of how things are done in all schools whether private or not. She has got one DD who went in to the local secondary y7. My DS went in to private school y7 (they're the same age). Ever since she has not stopped with her comments on private schools. According to her they give out good grades because the parents are paying for it. The school we chose is not expensive compared to most and they have a waiting list and only take in children who are already "good students" just like grammar school so I told Dsis that maybe that's why the students got good grades. She would not hear about it. She keeps on praising her DD's school even though staff turnover is high and it's clear that my DS's school is better (pastoral, dedicated staff, well-mannered children etc). I don't tell her that, I just nod, smile and say I'm happy you're happy and leave it at that. She's not jealous; DStepM helped us out with the fees and said she would help Dsis too if she wanted it. Every single time we talk she has to put DS's school down. She has the decency to be subtle about it infront of DS but she still has to say something. I asked her to not be so negative about something she knows nothing about. My DS is highly sensitive and quite fragile and he would be a likely target for bullying in Dsis' DD's school. He is very happy about his school and I wish that she could just leave it.
I'm not exaggerating: every single time I see her she just has to make a snide remark. It's like she's mad at me for not making the same choices as she is. It's gotten to a point where I want to go nc with her because she always makes me so upset and I feel so defensive around her just waiting for her "remark of the day". So AIBU to go nc with her until she has accepted to stop putting down DS's school ?
