Since I have to restrict my walking because of my bad legs, I have to plan ahead. Like I did yesterday. It did not work like I planned, though.
This is want I wanted to do:
– Go to my printing house further down the street
– Print the sheet of information about my new book
– Bring the book and these sheets to the library in Grünerløkka
– Collect a new lens I had ordered

So I walked down to the printing shop in Pilestredet.
The printing shop did not exist any more!
I walked on, feeling the pain in my legs. I wanted to get the tram from Holbergs plass to Stortorget, to get my new lens. On the tram stop at Holbergs plass it was strangely quiet. No people waiting for the tram. I noticed a sign saying there was no tram today. I had to get the “bus for train” instead. So I walked (!) to the bus stop. However, the bus did not follow the same route as the tram, and would not take me to Stortorget and my photo shop. What now?
I walked (!) all the way to Scandinavian Photo and bought the lens. Across the street there was a printing shop! They made those info sheets for me. One task accomplished.
Next stop the library.
How to get there? The tram did not work.
I had to take a cab, but first had to walk (!) to the cab stop.
By this time I needed a mens room. But of course, there was a toilet in the library! 
The library met we with locked doors. It had closed down because they were going to refurbish it. So my well-planned exhibition of my book and the sheets of information could not be done.
Now I really needed that bathroom. Perhaps I could use the bushes outside the library?
No.
So I walked (!) all the way up to a cafe on the street where I grew up, Karlstadgata. They had a toilet, they were willing to exhibit my book and the info sheets. In gratitude I had a little meal while there, and even sold two books to a very nice woman and her daughter  sitting at the next table.
Since the tram business was so difficult, I took a taxi home.
A bit later, I watched Magnus Carlsen win the World Champion title in chess once more.
A little bit of consolation after a day of too much walking.
