My nephew: "Bác An, what's your job?"

Me: "... erm... You don't know?" (I would have thought his parents told him...)

My nephew: "No. I don't. Or maybe they told me once and I don't remember." 

Me: "I'm a composer" 

Me nephew: "Ah! Like Ông Nội (paternal grandfather)."

The good thing is that my nephew is curious about others.
