prokofiev is playing in my head

Got a boy with Prader Willi in clinic attended by his mom and sister. Anthony shaked my hand, talked and greeted me in Chinese.

"Oh no, I'm sorry I don't speak your language. I can only speak Malay." was exactly what I said while I rubbed my hand with alcohol. And then I clerked the case.

At the end of the consult, I waved them goodbye and Anthony kept saying "xie xie" to me. 

"Baik lah aku balik study Chinese. Bagaimana mahu sebut sama-sama?"

His sister answered me but I didn't catch that with him non stop "xie xie". I just replied him with a "sama-sama".
