The boy who knows what he wants.
He starts to walk by him self. Walk to different direction that we intended too. Everytime you wanna catch, he will try to run away, even the speed not yet increase much.
No more want to be carried, but he wants to own his own direction. Once awhile when is tired, he will ask to be carried or he will just squat in the middle on the street.
Start to demand what he wants. See anything he likes, he will go to that direction.
Waving his hand stranger everywhere he goes. When he selectively wave on someone in the bus, train or even someone who just sitting on the bench in the centre of shopping mall.
