English girl meeting boyfriend's Polish friends

Any advise please?
I'm English and my boyfriend is Polish, we live in England.

Today we're meeting his Polish friends who have lived in England several years.
We're staying over but they speak hardly any English and I try to speak Polish but don't speak much either.

I'm worried what to do? I feel I may be sat there just listening to them not knowing what's going on.

Any advise appreciated.

Thank you

Tell the lazy sods to learn English or learn Polish. Other than that you will do fine.

Drink the first beer, then have the second one, and suddenly you will all be able to communicate.
