My group had done a presentation on ethers. And TBH I said and explained the most things.
When the next group presented someone said something funny...so the whole class laughed. The XXY teacher took off 5 points from my grade and someone else's grade for laughing -____-.
So now I have and 85 as a grade...and this other kid that was in my group has a 90 because she didn't see him laughing, and he hardly said anything in the presentation.
