It's depends on the situation really. He hides behind 'that' mask when he isn't comfortable I guess.
I hate stereotyping. I mean look at David Villa and his friend Samu Sanchez. All from Asturias, but they are warm, emotional and passionate.
Well, i didn´t want to make an stereotype. My bad.
I just wanted to point out that many people around the world identifies the Spanish with certain characteristics and they speak a lot about the latin spirit and so on.
But they don´t realize that Spain is pretty big and there are lot´s of different regions, and people from the north are culturally different from the Spanish stereotype. I´ve been in Asturias quite a few times and love it, but it´s not exactly a mediterranean way of life. People are charming, but they are "generally" a bit more reserved than in the south. They have a more "european" feeling if i may say so.... and the food is awesome
But back to the point, i´ve heard a few times that Alonso, when he was young, was not much talkative and a reserved person, and he certainly likes having his personal life in a low profile. Of course he can be warm and passionate, but not in a flamboyant "look at me" style. I see him as a true profesional, with lot´s of talent and passion for work, but i also see him more a calculating person than a emotional person, who likes to trust the people around him.
Also we are talking abut racing drivers. They are pretty "hot headad" in general compared to a normal person. I would piss my pants if i had to drive an F1 around monaco at full speed
