This happened this year (Year 11), in Chemistry. We made some salt crystals in class and the teacher let us have a look at them while she was teaching. I thought the salt crystals looked really cool so I got some on my hand to examine them a little closer, but then I realised everyone else was writing and that I should be too, so I quickly put the salt crystals away, forgetting to wash my hands. Ten minutes went by... My eye started itching. I rubbed my eye as most people would, but a couple of seconds later, it started feeling worse. I ignored it but then my eye started watering and my vision blurring. I really didn't want to tell my teacher that I'd gotten salt crystals in my eye (because who does that???), but the girl next to me started panicking because it looked so bad, so I reluctantly told my teacher. She looked at me like I was a right idiot, and asked how in the world I managed to do something like that. I was soooo embarrassed. She gave my eye a quick clean in front of the class with a wet paper towel, but waited until after the bell to give me a proper eye bath. I had never felt like such an idiot in front of a teacher.
