Bus driver

YJ & YF were playing in the room.
They climbed up to the bed and sat on the border.
Before I asked them to get down, here was the conversation.

YJ: YF, come, let me be bus driver. You sit behind. Come la.. come la..
YF not listening.. kept playing on his own.
YJ: haiya.. you ah...


Then, I forgot what happen, they changed place. YJ happily sat infront be bus driver. What about YF? I was wondering what was he doing as the photo below! :-D

I should say both of them creative? or superactive?
