Using please many times

One of the new craze for the little kid is a PS3 game. All the time and every day he is requesting that if possible he wants to have a PS3 with lots of ps3 controllers. I ask him what he will do with the controllers when in fact he is the only gamer for this kind of game. And he says that the controllers will be for him, for his daddy, for hi mama (that’s me of course), and for his little sister. I am telling him that his baby sister can’t play game yet because it’s still in my womb. But he says that when his baby sister will be born, she will play with the whole family. And so to end up, I just say yes to his request because every time he will request this thing, he will always use the word “please” many times.
