I've just caught myself out twice by writing something down as being **interesting for me**!
This is a typical Italian mother-tongue error, but Italian is not my first language. It used to be English, but now I'm no longer sure. 

And yet when I say the above phrase it sounds OK. I feel comfortable saying it, so am I right to use the preposition `for` in this way? If as a linguist said: "Grammar is about how people really speak, not about how they ought to speak."

Here is a [link](http://www.usingenglish.com/forum/ask-teacher/67751-interesting-interesting.html) which nicely sums up the difference between *interesting to me* and *interesting for me*.
