...at the moment, today,  have interrupted the "game of silence" because they must work well! Of course they can make all the noise they want. Then they put the kids on  stand guard, who behind a hedge, who around corners of houses, even some adult listen if someone calls to "cops" But someone has fun and says "ready ... ...." then kids run with the heart in  throat, and yell "Dad ... ... phone ... ... ... the cops"

Those stop working and they are so angry that you see cars going in all directions! but someone did them the joke and are up there laughing!!!
