"This is a train." Mama told me.
To me, the little colourful rectangle boxes which Mama made from play-doh looks more than a "train", I decided to place it in my mouth ^_^''' (Mama: too kiasu, the Toys"R"us play-doh is for the age of 2+, my little 18 months still like to eat especially colourful stuff, it has "nontoxic" sign and spells "fun to play with, but not to eat")
Shows you how the "usual" way I play the doh, alright?! Place this can, this way and then that way...
Step back to look at end result, satisfy? If yes, continue the game.
Sort the cans back to the holder. Have you noticed one can in my hand? Yes, this is "blue" (Mama: actually it was purple not blue, Gabriel likes blue but recently always take purple if both blue and purple are available, could it be he can't differential them?)
