Yamikani: Oh!

Takondwa: For example, do you know who is Graham Bell?

Yamikani: No 

Takondwa: He's the inventor of the phone in 1876; if you take night Courses you would know this. 

The next day, the same discussion took place:  

Takondwa: Do you know who Alexander Dumas is?

Yamikani: No

Takondwa: He's the author of "The 3 Musketeers", if you take night courses, you would know this.

The next day, once again:

Takondwa: And do you know who Jean Jacques Rousseau is?

This time, Yamikani got irritated and said: And you, do you know who Is Kondwani Phiri?
