👫 Is It Weird to Be Best Friends with Your Sibling?
Short answer: lucky you.
Not weird — it's genuinely lovely.
Growing up with someone gives you a shared history, in-jokes, and understanding that's hard to replicate. When sibling relationships mature into genuine friendship in adulthood, it's one of the healthiest relationship outcomes.
Not everyone gets along with their siblings, which makes it even more special when you do. The transition from "annoying brother/sister" to "actual best friend" is a beautiful arc.
Studies show that adults with close sibling relationships report higher levels of life satisfaction and lower rates of depression. So if your sibling is your best mate, you've hit the lottery.
