A teacher : Do i have to memorize all your names,class?

Students   : Yup,SURE!!

A teacher : GULP...huhu

This is the most hardest thing for me. To exactly recall the students by their names in the class. I tried so hard but still can put all those names in my mind. Arghh..kenape begitu susah nak ingat nama2 diorang nie? 

Setakat ini hanya ketua dan penolong kelas sajer yang lekat di mindaku plus a few students yang rajin menanya dan menegurku. 

Persoalannya:

Perlukah seorang guru @ pensyarah mengingati kesemua nama pelajar2 ketika mengajar?

Apa Kelebihannya?
