Shanshan likes to play "favorite animal" game wheneven she is sitting in the car: first one descripes what animal looks like and gives the first letter of that animal, and second person makes a guess.

Shanshan: My favorite animal has two legs, wears glasses, the first letter is D
Then she starts laughing.
Mom: this is hard
Shanshan: Do you want me to whisper?
Mom: yes
Shanshan whisper: Dad

<2>
Shanshan: Mom, let's play favorite animal again.
Mom: ok
Shanshan: this time I give one each time, and you give two.
Mom: why you only give one?
Shanshan: if i give two, my voice will get funny. Do you want my voice get funny?
Mom:......

Shanshan: My favorite animal has two legs, and she is good on cooking, and drives very well. the first letter is M
Mom: is she smart?
Shanshan: no, she is not smart, and she is not good on number. who is she?
Mom: is it monkey?
Shanshan: no, do you want me give you a whisper?
Mom: sure
Shanshan: it is Mom
Mom: Mom is not smart?
Shanshan: no, you are not smart because I have to give you whisper.
Mom: mom is not good on number?
Shanshan: no, because i have to give you lesson on number.
(Shanshan can sum two numbers together now as long as one of these two numbers is less or equal to 10 because she needs to use her fingers to count. She figures out a + b = b + a by herself. I am really amazed !)
