I actually don't know if having favorites in the fam is just a part of being a 'Filipino', or it's really a thing despite nationality 😅 But hey, I also experienced the things you've written even though I'm the eldest child in the fam. I can say that it really sucks to feel it. But once you get to know that somewhere out there, you are other people's favorite, then perhaps you'll feel so much better 😃 Nevertheless, you're right when you said that the world would be better if everyone is being treated equally.
