There was a very noisy group (at least 20 dotted about the plane) who constantly felt it was ok to shout across rows of seats to each other. A lot of people were sleeping and the crew didn’t ask that the shouting stopped or the kids runnng up down the aisle also stopped. It was frustrating and shouldn’t be left to passengers to ask fellow passengers to try to keep the noise down
