A Teacher who is Sorry

Today, after teaching 12 years, I make a mistake. In front of the class, i make fun of a student. At first it was okie, but when the rest of the class start laughing at her, she felt bad. I am sorry. Really. It is not nice to be make fun of. Leonora, i hope you can forgive teacher, I am Sorry to have make you so embarassed. You are still my good student that i treasure.
