A lot of us are still nostalgic for the good old days when the only things we’d have to worry about were getting to class on time and doing our homework. When you finish school, you might start to realize just how awesome some of your teachers were. They’re the authority figures who always put in extra effort when explaining topics to you. They’re the everyday superheroes who’d give you life advice. They’re the artistic souls who would spend hours on colorful signs and charts just to make learning more fun.
