I have a reputation, earned in childhood, as a person who corrects others. It's a character flaw that I'm quite ashamed of. I've spent years working on it and I'd like to think that I've got it under control, but the reputation remains.
I speak French fluently. Fifteen months ago my brother Al was hired by a French company and moved to France. He'd never taken a language class and spoke hardly a word of French, but has been working hard at it and has shown great progress. Al and I do not have a great relationship, so I originally declined our parents' invitation for me to go with them to visit him earlier this year, but relented when Al personally invited me. The trip was in May and was a resounding success. Because of our history I made a concerted effort to not take up too much of our parents' attention or speak for us with natives unless he asked for assistance. Because of our history and my correction habit I made a point of not acting like Little Miss French Teacher. I was actually quite impressed with his progress and told him that his French is way better than he thinks it is, which is true. However, there were two specific mistakes he made repeatedly that I now wish I had told him about.
Other than to say 'hello' when he is Skyping with my parents I haven't spoken to Al since May, but he's coming to stay with us this month. Should I go ahead and tell him about the two errors he was making, or should I let it go?
