Working on a holiday

Today is a holiday in the country I usually live in, but not where I am now. I got up late. I'm ashamed how late it was... but it's all the fault of being at the Opera yesterday evening - and that is of course Good For My Culture, right? - and not at all to do with the time spent in a Tapas bar afterwards.

I spent half an hour talking to S#7, cleverly avoided S#4, and devoted the whole afternoon to working with my coauthor who's here, whom I'll refer to as my Ununderstandable Coauthor (UCo). UCo is also the one who thought of going to the Tapas bar to begin with, so it's all his fault (it's always somebody else's fault). UCo and I are working on a paper which needs methods from a field we are not at all familiar with. So we get all the hardship of learning from scratch something new, without the help of an advisor or of anybody else, and while having "grownup" pressure to publish. Plus, of course, not only white hair abound on both of our heads, but also the inside of said heads isn't as smart as when we were students in the last century.
So it's all pretty hard, and there's always a very nontrivial risk that whatever we end up producing, if nonempty, will be declared unreadable by people who work in our field and trivial by people in the new field.

Tomorrow morning I will have to get up early to do my laundry, and then I have scheduled a Skype chat with PD#1 and S#7 to discuss our joint work. The next few days are going to be really intense.
