Sometimes in a classroom there can be a few embarrassing moments.
For a students some embarrassing moments can be being called on without raising their hand, not being able to comprehend like everyone else, and being the only one to raise their hand. Nowadays, being smart or “knowing everything” is looked down at and it promoted as a bad idea.
For teachers some embarrassing moments can be bad breath, not knowing what they are talking about and a strong bad body odor. Sadly, people in this generation would not hesitate to indicate these issues. Which there is nothing wrong with, but they wouldn’t say it in the nicest way possible.
