One scoops or two?

I was asked today why I like photography so much and I thought for a minute.  What is the easiest way to explain my passion to a 7 year old?  So I said "imagine it's the hottest day of summer and the sun feels like it's sitting right on top of your cute little head and the ice cream man drives up and tells you that you can have as much of your favorite ice cream as you want to cool down on this sizzling day. What would you choose?"  He said "definitely vanilla ice cream".  And then I said, "wouldn't that be the BEST ice cream ever?!?!"  And he said “yeah” with a huge smile on his face and then I said "well photography is my vanilla ice cream."  He paused for a moment and then he said "I like photography".
