A Great Gift Idea

My father just randomly gave me this weird blue book.

I first thought it was a diary... But when I took a close look to the blank pages, I saw the title on the top
"Great Idea No. __"
So I took another look at the cover, and read "The book of Great Ideas"

So my father looked at me and told me that when I will grow up and when I will have great ideas that will change the world, I should write them down in here and think about him... This is the nicest thing he ever told me...

My first great idea!
