You and your friend are sitting at the same desk in algebra class at school. He jokes and tickles you a little. You're trying to hold back your laughter because it's class time. Both of you are talking loudly.

"Rige and Akina! Stop making noise!" screams the algebra teacher.

Rige, your friend, starts laughing even louder, then whispers in your ear. "When is the end of the lesson? I want to go to the school toilet to smoke."
