Shhh, that's Paralympic soccer going on!
Bite your nails, bury your face in your hands - do anything but react as the excitement heats up.
Crowds at the Rio Paralympics delight in making noise but when it comes to blind five-a-side football, the whole point is to stay silent so that players can track the ball by sound.
That can be hard, especially when it's Brazil playing on home soil and in front of crowds more used to the usual 11-a-side, able-bodied variety of football - and its screaming fans.
