I had a terrible boss (russian) long long time ago, and he made fun of me (in front of others) the way I was saying: three, free and tree - it all sounded the same (and still I have problems). I&#x27;m not a native speaker also (bulgarian). Nowadays I&#x27;m grateful to our son (~8 years old) who corrects us all the time, and it&#x27;s kind of cool since this makes him feel good about it. I often would consult him when reading a book to him, how this and that is supposed to sound. He&#x27;s even starting to correct my grammar, and learned early on about etymology (I had to geekimize him).<p>Oh, that boss is long gone, he had another strange thing - correcting e-mails, people wrote to the point he wanted to correct one brit (and he was not the easy kind). I understand he also wanted to be helpful, but done privately would&#x27;ve been appreciated, done publicly - not so...
