What does a five-year-old know and wonder? (Updating)

Aidan is staring the clouds in the sky, "Dad, I see an artist riding a horse in the sky!"


"Dad, do you know daddy walrus and mommy walrus both have teeth, but mommy walrus has a smaller one?"


"Mom, Alivia and I have the same cup, we picked straws to match the cup, but we picked different colors. Why?"
"What do you think?"
“Hmm, because we are not twin!"


Aidan's teachere told me today that he met his old classmates after school and he acted like a small adult, saying "Hi, XXX, it's good to see you again!"


"Mom, when was the last day before you growing up?"
           ("Grow up to be like this? ... Well ... yesterday? 这好像是哲学命题了吧!)


"I'm tired to be Kira's friend." -- "Tired"？是累了还是厌倦了？不知该不该追问...


自问，我们准备好了吗？五岁的孩子已经开始在我们猝不及防的时候挑战我们的智商了。
