I got told to sit at the back of the class and keep quiet after that
Hehe, yeah, some teachers are really childish and petty. Our Maths teacher was just fun though and he never tried to say he was never wrong. I think it was him that taught me that if you never own up to mistakes then you never learn from them. A certain President comes to mind thinking about that. LOL. He’ll never learn.

Reminds me of that joke. Three friends, mathematician, a scientist and a politician get their brains valued for fun and are each given a cash value.

When the politician’s brain is rated as the one with the most value the scientist and mathematician are irate while the politician is preening.

Mathematician: “But I solved an impossible theorem! Why does my brain not have the most value?”
Scientist: “But I cured cancer! Why does my brain not have the most value?”
Politician: “It’s obvious that I’m a stable genius who is always right but just to set the record straight, why does my brain have the most value?”

So the brain assessor looks at the three friends and says... “Well both the Mathematician’s and Scientist’s brains have been almost worn out from the years of hard work... but the Politician brain is still in its “pristine, as new” condition... because it’s never been used.” ;)

My point is, if you never admit to being wrong you never learn ANYTHING.
