There’s nothing more annoying than hearing someone who has the sniffles in class, unless you have them yourself. Everyone hates being unable to breathe comfortably out of their nose to the point that they have to awkwardly sit there with their mouths wide open in class trying to breathe. Or, when you’re lying down to sleep and all you can hear is the sound of your own loud obnoxious breathing as you’re trying to fall asleep. Standing up during the most inconvenient time in class and having to grab a tissue is also a very unpleasant experience, and the act of blowing your nose is even more uncomfortable—especially when the room is silent. There is nothing worse than stuffy noses.
