Safety

Natalie's school is teaching safety recently. I received an email from her Header teacher about it:
"This month we are learning about safety. I couldn't think of a more important topic than what it takes to keep the little ones safe. I think it is of utmost importance for the children to know their address and at least one phone number in case they become lost or in an emergency. "

So, a few days ago, I was trying to teach Natalie to learn our home phone number. At first, I was telling her that in order to call someone using the phone, she needed to know which numbers to press on the phone in order to make the call. Then, I told her that when she's not home and if she wanted to call us at home, she could call the numbers: 650-xxx-xxxx (friends, you all know my home phone number, so I am not publishing here). I asked her:
"Can you please repeat the numbers to me?"
She paused a couple seconds.
Then, she said,
"媽咪﹐不如等我大個先學啦。"
