Do you think this guy was into me at all?

I'm at a bookstore and this cute guy comes way and he smiles a little so do I, but I walk past him. It's a really small bookstore so we walked past each other a few times and I was in one aisle he comes towards me, he's browsing books then like a few feet from he ties one shoe, then the next, then comes and stands closer to me looking at the same section as me. I didn't know what to make of it so I just kept reading the book I was into and so he slides past me as I'm sorry. Am I reading too much into it?
