If the person doesn't understand the concept it's quite difficult. It doesn't make sense. There are people who just
can't learn a foreign language. People who have no ear for music have a very difficult time even pronouncing their native language.
Maybe that's the case with this person. Even if she can read --as Perikles says--, the way the words are written, she
cannot perceive the difference.. That's what I understand you're saying, right?
I think you have a difficult task on your hands..
I've no idea what advice to give you..
