Conversations with Yaya

Yifan-Yaya's friend at school told his mom that he missed Yaya(he called her his "girl-friend") so much and he wanted to visit. His mom had to call one of our friends to find out where we live.
Me: Yaya, a friend of mine(who told Yifan's mom our address) asked me why are you so popular at school that your friend even misses at home?
Ya:(after thinking) I think it is because i am so beautiful!
Me: ??

The Pre-K class has been talking about birthdays this week. We had this conversation in the car on the way home from school.
Yaya: Mommy, when is my birthday?
Me: May, 31st. You used to know.
Yaya: But i forgot.
Me: Now you can try to remember.
Ya(change subject): Mommy, is our house on my side or Peter's side?
Me: You will see when we are there.
Yaya: Oh, it is on my side.
Me: Now you know and you can remember.
Yaya(loud complaining voice): You always want me to remember so many things, first my birthday, then which way our house is, how can I do so many things at the same time?
Me: .....

Peter turned the TV on himself after getting no response from me by yelling "Dian Shi(TV in Chinese)". Then after the kids watched for a little while, I dragged them out to get some fresh air. Yaya was reluctant to go outside.
Me: Yaya, we should enjoy the warm whether, pretty soon it will be all gone and we would not be able to come out and play after school.
Yaya: It is not fair!
Me: What is not fair?
Yaya: Peter got to do what he wanted(watching TV), you got to do what you wanted(coming out), how come I never got to do what I want(staying home and watch more TV)? It is not fair!

Me: Yaya, would you like to switch to a new school?
Ya: Why?
Me: Because the school at mommy's work has an opening now for Peter.
Ya: Yes, I can switch.
Me: But you love your new teacher here, and you have so many friends here. If you go there, at first you will know nobody.
Ya(in a very special tone): It will be fine. I will always make new friends.
Me: You sure?
Yaya: Sure, I am very nice and everyone will love me after a while. It doesn't matter. I can always make new friends and all the teachers will love me because i am good.
Me:(Nodding plus admiring)....
