The flight to South Africa was about 16 hours. Around hour 8-9, a woman was standing in line for the restroom (laboratory) and she passed out. It was very dark so, the woman really looked like some luggage. But I then saw rings on a hand. After further investigation, I discovered it was a woman. The attendant was called immediately. Everyone was around and it seems like everyone was speaking a different language. So, we all look at each other with the “what is the hell are you saying ” look. Finally the flight attendant came speaking another language, but one thing he did say was “sit down now”. That was very different for me, because I could not communicate with them.
