Happy christmas to you too. 
Yeah! I'm in such a good mood right now, and I can finally catch up on sleep again. I've only gotten 4-5 hours every night for the last few months, which kind of sucked.
Glad to hear your exam went well (and vectors have their appeal to some of us weird math people, haha)!
Oh, yeah, and hoe do you say "Merry Christmas" in Norwegian? "God Jul?"
