On Sunday we were stuck on arrival in a de-icing bay while a wicked thunderstorm rocked the city (no ground crew allowed outside, so all we could do was wait for the storm to pass). The couple across the aisle were getting very agitated, and neither spoke English. Unfortunately the crew didn't speak either of the languages that they did, but I had some really quite shocking high school recollections of both, so gave a very basic, but understood translation between the couple and the stewardess about their onward connection. I'd like to think if I am stuck somewhere not speaking the language, someone would do the same for me.
