This little girl is DEALING with things right now.
Alex Miller posted this YouTube video of the adorable Sadie, who is going through your typical kid stuff -- aging and mortality.
It all starts when she laments about how her brother has to grow up.
And then things get REAL introspective.
SADIE STOP BEING SO ADORABLE AND MAKING US FEEL EVERYTHING.
Remember, he'll always be your little brother.
At least you have each other.
DON'T. EVER. CHANGE.
