My extended family really believes in Chinese Tradition-- you know, those stereotypes you hear about where they favor boys over girls, oldest siblings inherit the family business, and you have to attend college/marry someone who is also from East Asia or else you get disowned? (I'm Taiwanese btw, so this means to my grandparents Chinese boys are a big no. There goes like, more than a quarter of the male population hahahaha!)
Yeah anyway. You see, I'm female, which kind of automatically means I don't matter at all in my extended family. Then, no less, I get along much better with my mother's side of the family, but since she married into my father's family (and it can be said that she is 'no longer a part of her original family',) it's frowned upon for her to interact with them too frequently, which means in turn, I don't get to see them very often either.
Then there's my father's side of the family. Oh my god. Despite the fact that I, as an ideal Taiwanese granddaughter who continually seeks to 'bring honor' to my grandparents, feign complete happiness and subservience, I'm still pretty much the "other side of the coin" to my older brother who is literally this perfect human being who can do no wrong. Because he's the oldest grandson of the oldest son of the father's side of the family. (It's that age and gender hierarchy I mentioned earlier.)
Oh and that thing I mentioned about disowning? Yeah, technically I have five cousins on my father's side, but four of them have been essentially disowned, so I guess I don't get along with them because I'm not supposed to talk to them/mention them.
So TL;DR: Yes, on the surface I get along with my extended family that's uh, still considered part of the family, but I don't know why. I have to try so hard in order to stay in good standing with everyone and all I ever get is a bag of crap handed back to me. I guess it's because I believe in the traditions quite a bit myself, so I can't bring myself to disobey my elders.
Other than being super bitter at them on a pokemon forum hahahaha
