"Talking back"

Before i forget,

We went to ah ma's house yesterday, Bernice was playing with my soon-to-be sis in law. And, after that Bernice managed to get $2 worth of coins from her. At night, bernice got another few dollars of coins from ah ma again. So, she was pretty rich yesterday.

While we were going home in a taxi, alot of conversations took place between bernice and ah ma,

This is the only one i can remember enough to pen it down.

Me: Dear dear, next time you cannot take money from jie jie (soon-to-be sis in law) ok?
Her reply had me kow-towing to her and banging my head agst. the wall.

Bernice: i only take coin.


haha, i tried consoling myself that she is sincerely not talking back and the reasons i have come up with are
1) this is the limited vocab she has
2) she really thinks money is different from coin. money is notes, and coin is coin.
3) She can be a future banker, coin is really smaller in value than her version of money, and thus the word "only".

That's all i can think of.
