One of the problems with good language and good ideas is that more than one person can come up with a good thought or idea – honestly, without plagiarizing the idea.

We are now all completely jetlagged, thanks to the baby, who does not care to get back to regular schedule. He wakes up at 3am with this soft, almost creepy whisper of “I’m hungry?” I’ve had about eight hours of sova total over the last three days and have started hallucinating a little (“Yes, Your helighet, I would love some easel paper…”)
