Being a teacher must be seriously difficult work.

Between correcting those endless mounds of work, establishing authority in front of a class of little crazy people and the dreaded parent-teacher meetings, I don't really envy the life of a teacher. Besides the rules and regulations that teachers must abide by, unfortunately some can suffer criticism about the stupidest of things and it can be a seriously hard transition going from a long Summer back to school. When you're teaching a class of kids, I presume you have to mind your p's and q's and especially your language so the little ones don't go home entirely potty-mouthed (although, these days, there's not much helping them!) One teacher, otherwise known as Reddit user dustofoblivion123, was teaching a class when she made the one mistake you DON'T make during a Science class. Uploading a post entitled "A science teacher's worst fear", she supplied us with two Snapchats that show the mortification every adult feels after mixing up 'orgasm' and 'organism'. As if it wasn't bad enough, she made the faux pas in front of the most easily distracted - a class of 30 13-year-olds. LOVELY. I can't even begin to imagine how she got out of that one... Have you done anything mortifying in class or college? If you have something you'd like to share with us, get us on Twitter here, on Facebook here or you can drop a line to hello@her.ie.
