hide things at her back

hiding game is back but this time she needs no pillows or blankets. she learns from the book, people could hide their hands at the back, she likes to do this silly games 500 times a day.

and i think i am the only one in this world understand what is she saying when she "talks" with her hand at her back. 500 times she "asks" me where is the paper. 500 times i pretend to ask her where is the paper (with big question mark on my face). 500 times she shows me her hand and the piece of paper she is holding with proud and happy face. and 500 times i shouted "there it is!! you found the paper!!" with full surprise.

besides hiding, she likes to walk with her hand (sometimes both hands) placed at her back, as if she is thinking something deep and that seems a bit odd to a 15m girl.
