I am an English guy, teaching at an educational camp in Poland, which is hosted for Poles, Czechs, Slovaks, and Hungarians. Everyone seems to be able to speak English well enough to have a conversation, and the classes themselves are taught in English. However, understandably, when they are together they tend to speak in their native tongue since it is easier.
I am a shy, quiet person and generally not great at socialising, but there are many talented, interesting individuals at the camp so would like to socialise with them from time to time.
I am unsure of how to go about doing this when they are speaking another language. If I stand around for a while occasionally one will translate briefly what they were talking about which is nice, but then I can't really find out until it's already been talked about.
Are there any ways to improve my interactions with these people without directly saying 'speak English' (I'd guess this is rude since I am the visitor to their country after all...)?
Long term I'd like to learn the language but Polish seems quite hard currently!
Any advice would be appreciated.
(Currently, everyone at the camp ranges in age from about 17 to 20)
