btw. do you agree with the last sentence? I don't, I hope Messi stays this way, I don't want him to let us in.
It's true not a lot of people know squat about him. A few locals I've talked to seem to think that he's not the most intelligent kind of guy based on the mellow subjects he talks about in interviews (familia this, familia that etc.).
I doubt he'll open up. There are just some people that are closed off like that. My little brother is like that: always giving short non-descriptive answers, not being able to share personal experiences and generally reveals very little about himself (I'm often surprised at how little I know about him). It's just how people are.
In Messi's case I almost think it's a good thing. It's always clear in all interviews that football comes before anything for him and that's what matters.
And wtf is up with that other article? Does every reporter really need to bring CR up in every Messi interview? If I was Messi I would've walked out of there in anger. Rival. Pffft. Not even close.
