Wait do all three of you live together in one house in your 30s? That's awesome!
EDIT: Just to be clear, this comment is in no way intended to be sarcastic! I really think it's amazing for three brothers to live together in their 30s. The notion that each has to go their separate way after one turns 18/21/25 is bullshit. Life is more fun together and there's inherent economies of scale as well (both financial and social).
Now as an adult I've moved to the US, where it's much more common to move far from your family. I grew up expecting that I would always have my close family near, and I still struggle with the fact that's probably not going to be the case.
I would absolutely love to live near or with my brother and parents still. Definitely would need a way that would allow us to have private spaces when we want, but I miss being able to see close family with just 30 minutes of traveling.
