I treat it like a Livejournal (minus questionnaires… generally)
I am too shy to send messages to people I want to be friends with, and I only send replies when I’m in a very specific mood.
I don’t post enough pictures of myself, apparently. I still think about this one drama-inspiring post from a long time ago wherein someone was complaining about another user who supposedly made a big deal about being curvy, but never posted pictures. The post probably wasn’t about me but I still think about it.
Putting my iPod in my pocket without turning it off, so that Tumblr posts something I started writing but didn’t finish.
