"What do you want...."

It`s my birthday in twelve days time, and my parent is now asking "What do you want for your birthday?"
My answer: "I don`t know". And, I really don`t know, there`s nothing I`m really wanting. I`m expected to come up with a list for her tonight, but what to put on it...???....
So what do I ask for? .... I quite fancy getting a new car, or upgrading my laptop computer, but I can`t ask for them!
