Mahjong Prince in the making?

Last night as I was watching Caden play with Kimi's masak masak food toys in the container after my dinner, he reminded me of our fav hobby that my ah man and I used to do in the past.. Mahjong!! He was using both of his hands to "wash" the toys in such a manner that it is exactly the same way that we "wash" our tiles during a mahjong game.. hmm.. perhaps, he has inherited our mahjong genes?? To me, it also seems that he's frustrated with seeing the toys packed neatly in the container, he sees a joy in messing them up!!!
