Lots of Dollars

We took Wm to the Lego store last weekend to poke around - his favorite activity.  While we were there, he fell in love with a giant pyramid lego set.  He said he wanted it for his birthday and I said, "well, Wm, you can have it for your birthday , but it's very expensive, so it will be your ENTIRE birthday...that means you would get no other presents!"  He goes, "I don't care - that's all I want!"  He then became obsessed with staring at it online and asking us to count how many days until his birthday.  Later, we had to go grocery shopping.  While we were driving to the store, Wm asked, "how many dollars is the lego pyramid?"  I said, "It's one hundred dollars, man."  Wm's eyes got huge and he goes, "we cannot spend ANY dollars until my birthday!"  Then, the entire time we were at the grocery store, he kept insisting we didn't need to buy things and asked continually how much the food was going to cost.  I think he'd rather starve than not have legos.  When we paid for the groceries, Wm moaned, "now we'll NEVER have enough dollars!"  He was depressed all night thinking we had squandered all our lego dollars on something silly like food.  I had to promise him a zillion times that we could still afford to buy food until his birthday.
