Or when they repeat what the teacher said "just to clarify"
Teacher: "the sky is blue"
Student: "just to clarify, the sky is not green but blue? Great great got it"
True. After every question, it gets a bit annoying (especially if it's math where personal stories are irrelevant), but I usually just take the time to read instead. It's all good. :)
