I love this!!!! The practice of talking yourself up and letting friends know when you're feeling yourself (and giving it back in return) doesn't strike me as vanity. It seems like a giant middle finger to the societal norm that tells us we can't do these things, and can't find ourselves beautiful sometimes. To me, vanity would be staring at myself in the mirror for an hour, picking apart everything and pulling and prodding and wishing I could change things. I never feel more vain and self-centered than after I've beaten myself down.
