Meowing

i have no clue what made this happen again but the guys in my theater class have been meowing and my poor old ass theater teacher is starting to get mad. Not gonna lie it is really funny to me when everything is silent and then you hear random meows that sound super real. She's been really chill about it for like a month but now she's getting fed up with it today. It was so funny to me because she randomly turned around while explaining something and pretty much yelled, "STOP MEOWING", the second she said that around 8 or 9 people started meowing and then the whole room went silent. She then started talking again and someone said something that I couldn't hear and she got mad and said, "Stop making noises, stop playing the random music and stop cat calling each other!". She probably heard people calling each other daddy or something.
