Museu Picasso

Surprisingly I was able to get up before noon today (I don't want to specify why surprisingly) and, moreover, found an idea of going for mass into the old cathedral of Barcelona nice. Of course I would not understand (which, on the contrary,  might be sometimes an advantage :) ) and would not stay for the whole time. But seeing the nice place again after a year and spending little time "alone" was attractive.
Since it is a long journey (35 minutes by train) I of course wanted to make use of my visit to BCN center and planned to join Eddie and others at swing dancing place in Parc de Cuitadella (and possibly do something else with them afterwards).
For some reasons I don't want to specify I was only able to come to the Parc 15 minutes before the end of swing dancing and nobody was there (already?), maybe because of slightly rainy weather.
My plan included two options: Casa Batló or Museu Picasso. Since the museum was on my way first, I checked it out and it turned out that I hit by accidence the only day of the month, when the entrance is free (first Sunday of each month) which saved me either 9 or 6 Euros! Nice!
The temporary exposition was the best of the museum. It showed a period of Picasso of mixing humans and nonliving objects together in a way that you cannot recognize one from another. Among nonliving objects almost always was a guitar so the museum is very recommended for all lovers of this instrument (or lovers of the shape of the guitar as well).
Beside that there were some sketches of Picasso projected and they showed that besides being the founder of Cubism, Picasso was the founder of the graph theory as well :).  The pictures were exactly like from graph theory textbooks! Some of the sketches (or proofs?) included really really huge graphs, probably some extensive case analysis:) Despite the prohibition of taking the photos, I include here one very small "graph" of, as you can easily guess, guitar.

Sorry for the "mobile" quality, in reality it's much better.
