Guys and Shoes? I WAS WONDERING...? 5 stars to best answer?

I told the guy I have a crush on that he had bought the wrong shoes. Insted of Pumas which is what he had, he needs Nikes! I love Nike. (I was kinda kidding around with him) but today when a saw him he had on brand new Nikes!!? I complemented them but am now wondering if he got them because of me??? Why does he care what I think all of the sudden?
