Teacher Showing Not Enough Attention?!!

One of a parent was boiling with fumes appearing above her head, saying:

"You didn't show enough care and love towards my daughter during your teaching!! What type of teacher are you?!!"

Apparently that certain mother of one of the students from my class does not know exactly the roles teachers play in the society nowadays. She blames my form teacher for not showing enough care and attention to her daughter, claiming that it was the main factor which leads to her daughter's grades to flop. This is totally absurd. She should have brought a giant-sized mirror and see her own reflection to understand that the major cause of her daughter's grades to flop was her own daughter's lack of discipline and paying no attention during lessons. She expects the teacher to stand right in front of her daughter holding a history text book glaring and speaking every single word in front of her face?? A teacher's job is similar to a burning candle, enlighten every students path not a torch light that shines directly onto an individual.
