Learning Korean

Today I asked HyeonWoo to teach me Korean. He's the Korean boy btw.
He pointed at the picture of the rice, and told me that it is his favorite food.
This is actually his first time striking a conversation with me. I've actually hesitated a long while to try speaking Korean with him, after all my job is to speak only English to the kids.

Anyways. I quickly answered him, "Rice? It's called 'bap' in Korean right?"
He nodded.
"Can you teach me Korean HyeonWoo?"
He looked kind of hesitant and confused.
"How do you say hello in Korean?"
"An-nyeong?"
He was as blur as ever.
"How do you say apple in Korean?"
"I don't know."
"What about orange?"
"I don't know. My mother haven't teach me everything."
"Oh, ok. How do you say goodbye?"
He was thinking hard.
"An-nyeong?"
"Ya."

I think I stressed him out quite a bit so I stopped asking. Plus Haddie was interrupting big time trying to get me help her color. It's funny how he speaks Korean but when asked of names of random objects he can't recall. =)
