This is not granted always. It depends on the people.

The problem is that you are trying to learn spanish being inmersed at the same time in another similar language but with different orthographic and grammatical rules. And you see examples of the non-spanish version everywhere in your journey. Should you use a 'B' or a 'V' for that word?. Sounds the same but is often the opposite in the two languages. Lots of people have problems with that without even noticing.
