My participation to this program was 3 weeks long, at the end of Autumn in Cherkasy. Despite a program "baseline" orientated towards help in orphanage, I passed most of my time helping out English teachers in a working-class school. The teaching team was really happy to have a foreigner helping them, as well as the pupils (between 7 and 17 y.o) who, for most, never had the opportunity to speak to one before. Some time in orphanages came on top of that, mostly playing with the kids.
Ukraine is a very nice country I must say, unfairly forgotten by tourists, full of sincerely kind and helpful people, who were really happy to share their culture. I plan to go back as soon as I will be able to, but this time, maybe more as a road trip.
