Perfect volunteer trip

At first my father was worried about my safety because my parents thought China was the safest country and Greece was not very safe. But this trip changed my parents' minds. Greece is safe (not absolutely, because there is no absolute security in the world), and I am worried that the people I meet are not very friendly. But the friendliness and enthusiasm of the people broke my worries and my nervousness about coming to a new place. Get along with them, I learned a lot of things, other countries' culture, customs.
