That mirrors my own childhood as well. It's actually things like like standing up when I wouldn't have expected it. As an example, I've overheard my preteen chastising her friends for talking about someone behind their back. Another example is our 2nd grader bringing home an assignment the other day where she was supposed to write what she wanted to be when she grew up, and her answer was "kind."

Like holy shit kid... they're both miles ahead of where I was at their ages around topics of justice and the skills it takes to maintain social cohesion, and they're so much braver than I was and willing to use their social capital to stick up for people that can't themselves. Then they'll come home and get in a fight with each other over a spot on the couch or something insignificant like that.
