best friends

Is it just me or are preteen brother and sisters supposed to irritate each other and not love hanging out together, holding hands, and definitely NOT voluntarily hug and cuddle?? I mean, never, ever refer to one another as "best friend." Right!? (Cue my sobbing.)

I have literally never witnessed a more genuinely loving sibling relationship. And get this- they treated their PARENTS with the exact same level of adoration and respect. Whatever it is these four are doing, they are doing it right.
