My cost of doing nothing on Nov 19

Tomorrow, after quite some time, I can afford to do nothing and have it cost me only 13 euros (my all inclusive rent divided by 30), 13 instead of 60, 82, 70, and especially 80 or 100 or in some cases 150! Oh yes, hotel rooms cost, around Europe. That will contribute to my rest - peace of mind while doing nothing. Dolce far niente, right?
