River seems to have gotten a lot of her father's personality traits. Normally, I would attribute that to nurture, but her father took a nice 7 month break from being a parent (though, to give him credit, he is now reemerging as, if not a parent, a sort of uncle-figure).
It's so strange to see her start being loud and silly to get a person's attention. She loves having every person in a room watch her. She's purposefully silly and loud and fantastic.
I'm just glad that I can see these traits as something I loved in her father instead of just reminding me of the pain he caused.
