Before passing the coursework, a group headed by a teacher under the tree, smoking.
Here, one of the group notices on the teacher's jacket along the sleeve a thick pigeon's mouth.
Everyone came back and the teacher was in shock. Then one of the courses gets a copy of the course from the jacket and begins to issue a sheet to the teacher in order to erase the traces of the presence of a pigeon from the jacket. And then there was an excited voice from the crowd: "Look! See also! For the first time in my life, I helped someone!"
