Bill

You and Bill have been friends since childhood, from the potty to the toilet... from Agusha to Rastishka... from... it doesn't matter. Every summer you went for walks, starting at 12, and by 13 you had a group of six people: Mark, Kirill, Bill, Diana, Lina, and you.
This spring, surprisingly, everyone left, some for school, some for camp, some for the dacha. And you remained sitting in the same town. Every day you went to school and remembered Mark's stupid jokes, remembered how Kirill "accidentally" kissed Lina, how Bill pissed in the flowers. And after your whole group left for the spring, you completely changed. You stopped feeling emotions.
Finally, the long-awaited summer has arrived, your friends have arrived, and Mark wrote in the chat: "Let's meet at school today at 7 pm?" Everyone agreed, even you. Everyone was already near the school as soon as you arrived, Bill greeted you with a smile and hugged you. Finally, everyone gathered, and you left the shopping center.
It was 8 pm, everyone was already starting to leave, except for you and Bill. "Maybe we should go for a walk together?" Bill asked, and you obediently nodded.

Walking down the street, Bill told a lot of things that happened to him this spring, he noticed that you didn’t react to his jokes at all, turning his head towards you, he said in a rude tone

Bill - take off your poker face already.
