Laughing through a uni presentation

Anni and Lauren in Nutrition tutorial where everyone is doing their group presentations and are being assessed. Everyone gets a paper where they peer mark each other’s presentation. There are different boxes of criteria and what it’s out of. For example “gave background knowledge of culture” and that would be out of 5, 5 being the best and 1 being the worst. There are 6 rows (obviously meaning 6 different presentations). Before anyone even starts Anni generously decides to give everyone full marks for their presentation and writes that down on all 6 rows. Lauren looks, cracks up and says “There’s only 4 presentations today and one of them’s us.” Oh damn, that will be a give-away to my assessor who collects all the peer marks in the end. Anni cracks up. Then the whole tutorial, every time anni and Lauren even look at each other they crack up and try soo hard to hold it in while other people are doing their group presentations. Sometimes they were successful, other times they just lost it in inappropriate moments. One time anni laughs so hard that tears roll down her face. The whole 2 hours become torture trying to hold in the laughs. Finally anni’s group gets up to do their presentation. Anni is the first one to speak. She starts, gets through about 5 sentences and then bursts out laughing in front of the whole tutorial and the assessor. Everyone is silent. “Sorry guys, we had a personal joke before and I can’t stop laughing.” Lauren starts cracking up behind her. Anni keeps trying to get through the slides but keeps laughing, eventually gives up and lets someone else do their part. Anni and Lauren crack up throughout the presentation and finally the class ends and they breathe again.
