Yesterday was a joke. A black student enters the audience who is late for a couple. And there was only the last chair that stood next to the board. I told him to take a chair and sit down. He approaches looking at the chair and says I can’t sit on him because he’s white. I am in shock. I think Nietzsche makes statements. I’m sorry we don’t have black chairs. After my words, he swallowed. And it turned out that he didn't know Russian well and couldn't express himself, the chair was covered with tiny crumbs, once standing near the board.
