Looking at my parents and their siblings (varying degrees of almost no contact to some contact with one exception that is good), and looking at my sibling (really good), it has nothing to do with you. It’s just, two people that shared an environment growing up, and those two people can be close or not.
I feel very grateful for my sibling, but that’s just it. We happen to have the personalities that match.
It’s not your fault.
Don’t do this if you dislike the orange/chocolate combination. I really dislike that, I don’t know why. I don’t like dark chocolate, prefer milk chocolate, but I like oranges. Putting them together will make me throw it away.
But it looks like a good recipe for those who do like the combo!
