Because i have at least 4 classes or 100 students each semester, i have difficulty remembering their names. And because i hate calling them by the colour of their hair, i have to remember their names.
But before i can remember their names, i tell them to tell me how.
Because they have to tell me how, i can remember everyone's name by the end of the first class.
But if i can't, it certainly ain't my fault.
