That feeling you get when you say something and someone else disagrees and then you prove that you're right. Then you can say 'I told you so' but not in a rude  way or anything, more of a joking way because that is nicer. 

You sit in your science class, going over the answers to the packet your class had been working in small table groups. The packet is about nutritional value and what you should and shouldn't eat. Your group was called on to answer a question. The question required you to pick out which food label was the most healthy for you.
Before, when your group has been discussing about what the correct answer was you had gotten something different from the rest of the group. Your label had almost the exact same thing as theirs, but it also has a bit of fat while theirs had no fat. You had initially chosen the no fat label but remembered that your teacher had told the class that a little fat was needed to stay healthy. You had tried explaining this to your group but they were set against you, nothing would have been able to change their minds.
Anyways the teacher called on your group to answer and one person spoke up a said the no fat label. You then told the teacher that you disagreed and why. She didn't have an answer document and she wasn't sure which answer was the right one. So she decided to go across the hall to another class and ask that teacher what they had gotten as an answer.
The class all got up and followed your teacher out into the hallway. You were just behind her, paper in hand, as the rest of your group tailed you, the rest of the class after them. Your teacher knocked on the other class's door. They opened up and we shuffled in.
Most of the class fit into the room to watch as your teacher asked the other teacher, she wasn't quiet about it either. The other teacher looked around her classroom remembering what they had gotten. Then she told your teacher that they had gotten the label that you had chosen. You had been right.
Your class went back to your classroom and resumed going over the questions. You were doing a little victory dance in your mind, though, glad that you had been right, winning against basically the whole class.
The End

(A/N) This actually happened to me, and I was pretty happy as if I had just won some small war. This is the longest I've written so far ☺. Have a nice day 😺
