Laughing

Ok so I go to a really small school that has 350+ (not more than 430) that’s from pre K to grade 10. So I’m in 9th grade btw, so at lunch I have it with 6th to 10th graders. I was at the line to pick up my food and the line goes so slow because the woman we have to pay is so slow and stuff. So I was in line behind 10th grade boys (I know them) they randomly started singing drag me down. I was laughing so hard they asked me to join them so I did. 
At the end a teacher yelled at us for 10 mins straight just to tell us to quite down. We ended up going to the end of the line😑
