I’m watching you while he’s watching me.
There is a lot of sitting done in Madrid, and a fair bit of watching. The gent on the left was there when I set off to see a few galleries and have lunch, and he was still there when I came back 3 hours later. Even though beer is amazingly cheap in restaurants, there are those who still prefer to sit in the park with a tinny or two. Possibly because there are more suspicious types in the park to keep an eye on.
