Blaming For No Reason

My mom was blamed for no reason actually, right after my mom told my aunty about selling the tanah peninggalan arwah opah dan atuk. However, this kind of thing has been discussed earlier like months ago and already agreed by all of the siblings. My mom act as the orang tengah which manage and tells to all of the siblings which is not in conversation to bring on the selling topic a month ago. She announced the decision in Whatsapp group and then I don't know why my aunty get mad about this. But get mad to my mom only. Why? Can you tell me why? I do really want to know why!

My mom didn't sold the tanah and take all the money, yet she never ever do that disgusting thing.

It comes to worse when my aunty didn't join us for my mom things, engagement and solemnization. She said, the problem she don't want to come is:

My mom didn't come and invite her at her house. My mom actually Whatsapp-ed her and ask here to come to her house but there is no reply from my aunty. She left the bluetick only. Does this kind of thing is my mom fault?

Hey, or you want my mom put her knee down in front of you?

My mom didn't say anything, but my uncle and other aunties keep on sindir/perli. For me, there is nothing to talk and to think for something/someone that never ever want to be with us.
