My sister thinks I treat my friends better. We share some close friends and all went away together for the weekend, which ended up in an argument between me and her that I treat them differently, nicer, than I treat her.
We don’t always see eye to eye but I think I just don’t feel as relaxed around her, it’s not intentional, which I did tell her. I find her quite prickly and highly strung at times, unsure when she is next going to pull me up on something.
So actually, yes I may unintentionally treat her differently, but is it necessarily unreasonable?
