My mum snaps and picks at me, and if I was to say anything to her that offended her even slightly, or said something in the wrong tone she would give me a death glare or shout at me or tell me to leave. But my sister speaks to her like absolute shit and my mum is overly nice to her all of the time, and will try extra hard to get my sister to be in a good mood with her. I confronted her about this and said it made me feel shitty, and she said ‘I treat you differently depending on your needs’. But I don’t understand that. Is this a normal parent thing or are you and your siblings treated the same?
