Me : What have you built that is so amazing?
Girl A : A public toilet.
Me : I am impressed with your ability. By the way, why do the toilets have no doors?
Girl A : It's ancient Roman inspired toilet.
Me : Oh! I see....How did you make the sinks? How did you put on the water? How could you make all these stuffs by yourself? I am not even sure I can build them myself. You are better than me in building.
Girl A : Well, it means you are a successful teacher.
Me : Why is that?
Girl A : Yeah, I am smarter than you. You are doing a great job because your student turns out to be more intelligent than you.
Me : I see....
Girl A : and prettier too he he he......
Me : Okay....So I am a great teacher because you are smarter and prettier than me? That's interesting.
Girl A : (giggles) Yes. Would you try to sit on the toilet and poo?
Me : No, I wouldn't.
Girl A : Why not? It works you know..You should try.
Me : Because I am a great teacher and a great teacher will ask her intelligent and pretty student to try on her own toilet. Come on.....
