You were at high school, it was 10:00 in the morning and you were at Algebra class. Like usual Sheldon was answering all the questions but when he misses you take the opportunity and answer. He was surprised because he never misses a question. In the end of class he went and talk to you.

Sheldon: I ask you to not answer my question anymore, and im saying this politely, we can do it in the bad way
