She told in her blog post that Spanish people are quite warm and open always take up the initiative to talk, if they find you worthy enough. If you enter a pub, for instance, you can't avoid finding someone to talk to. :D Even if they don't understand a heck of what you're speaking. xD She didn't like the cappucino there, tough.
I - personally - never experienced that. For some reason they tend to avoid me. xD
