The students are asked to go to the other classroom and find an open seat. If all the seats are taken, they must ask to share one or sit on the floor. The host teacher simultaneously explains that there has been a problem and asks if it would be all right if the students host some displaced students for an indefinite period of time. The teacher emphasizes that it would be an admirable gesture to invite them over. The visiting teacher begins to send students over, with the entire room eventually being filled.
Students end up sharing desks or sitting on the floor.
It may become noisy. Both teachers explain to their students that the class will proceed. As the lesson begins, students may complain that they cannot hear or learn under such crowded conditions. After a few minutes, the teachers stop to hear specific complaints from the students. Typically the host group voices the loudest objections over losing their seats, privacy and freedom, despite having inviting their guests to come.
