Me and some friends of me play some card games in our classroom, when we have some spare time at school. There will always be someone talking too loud. If we have our own discussion, then the others talk as much as they want, but if we are for some reason silent, we will sometimes join in, and sometimes troll them. When I eavesdrop while playing cards, I will often comment with: "It's funny what you can hear when you shut up..."
