The HF20 and all i feel like this was a month ago :)
Slovak and Serbian are for me almost the same, but only because i speak them. both are in the Slavic category. Short history :) ottoman empire wanted to visit central europe but they had some troubles at the borders (i think it was an issue of bringing weapons through the border) so they stopped here around Danube. So Maria Theresa and some after her decided to give land to people if they move here so they could monitor the border. No one really wanted to be in Padina, as it is an and of sandy terrain and first sign of water is at 40+ meters. But then Slovaks came and said they will try to dig the wells :) and until now Padina is 94-95% made by Slovaks, we have a slovak school, we speak (some kind) of slovak and we live in Serbia.
