In celebration of #WorldTeachersDay today, President Buhari blessed us with a rare tweet that allows us a tiny insight into his childhood.

On this #WorldTeachersDay I remember Kasimu Adamu Zangon-Daura, my Junior Primary School Teacher. Who is the first Teacher you remember?

Lucky man, that Mr. Kasimu Zangon-Daura. To be remembered so fondly by a Nigerian President.

Wonder if Senator Sani Nasiru Zangon-Daura  is in anyway related to the President’s teacher. #JussAskin!

But the more important question here should be: What is a “junior” primary school?
