Context: Soowei having her observation and the class was rather quiet. They had just learned the properties of the various triangles. And it was evaluation time.

At this current moment, Alden decided to raise his hands. Actually, Alden is rather brilliant, so when he raised his hands I thought he wanted to help Amirah with the answer.

Soowei: Yes Alden?

Alden: Miss Sim, who is pardon?
