Within hours of arriving into Zagreb, I noticed a significant difference in my mood as compared to when I was in Lviv. Although I had less than four hours of sleep back in Budapest and the weather in Zagreb was just a bright and sunny as I remember in Lviv, I was remarkably cheerful. It was a strange feeling that I couldn't quite put my finger on, but I couldn't stop smiling. I strolled through through Zrinjevac Park in the middle of downtown Zagreb for a half-hour before it finally dawned on me why I was in such a positive disposition - the people here are smiling! They seem so much happier than in Lviv! Even after three weeks of traveling through Ukraine, I still can’t get over how ingrained the simple act of smiling is in my life and how significantly it effects my mood.
