Singing to myself

Nobody came to Lucia practice (Lucia was this monday, but we're having our christmas party on friday so we're having a Lucia celebration then) today so now I'm sitting in my office singing to myself.
I should be working, I have spent most of the day reading a very good essay on gender and clothing in two versions of the Tristan story by a student I have been mentoring, making some comments for her.
Now I will have to continue with my background chapter on textile production.
