A relief teacher shared a joke with me just now regarding this class 1 R.
She was saying that the whole class of 1R had to stay back for punishment. Just because they're making fun of the teacher whose name is Mr Tan. The joker of that class actually rename Mr Tan as MRT...So, if you were to look at the spelling carefully, MR Tan (read: MRT). And the teacher is fierce according to her. HAHA. Who would think of that word sia, MRT... So, because of that the WHOLE class got to stay back. HAHA.
So, don't be too fierce with your students or else, they will create names behind your back. hurhur.
