Everyday I walk the same path to work, the same streets and views. I used to say "good morning" to the traffic police officer that kindly would stop the cars so I could cross the street. He doesn't work there anymore. I now say hello to a very kind indian shop owner that is hanging out his shop items at the same time I start descending the Rua do Monte Olivete. 
When I get to Praça das Flores, first, I always look up (nice trees that let in the bright sun) and then I look around... usually at the same people... that, for some particular reason, are already sitting around doing whatever it is they do. 
I repeat the whole thing in the afternoon, on my way back home. It felt good for a while, but now I'm a bit tried of it.
