How many dressing expressing do you know?

Hi NinaZara,

Why should we refrain from correcting a teacher in front of his or her students? Well, I think I can figure that out on my own. But if a student knows that the right alternative is alternative A, and the teacher erroneously states it's alternative C, then what should the student do?

Englishuser dear,

Why should we?Because it's more polite and save faces.I guess you've figured that out. And as to your 2nd question, well,it's up to her, really .
