Karolina, I had that same feeling of nature in the city when we were at the gardens at Zilker. There, however, people were not rushing around quite as frantically as they were on the campus (because it was a Sunday at the park vs. a Thursday at a very big university). It was an interesting contrast in the people, but there was no contrast in the relaxed state of the animals (i.e. the fish at the park and the turtles in the pond). It is nice to know that they will relax no matter what time of day, or what day of the week it is. Only humans are controlled by the clock.
