I am interested in your experiences with people when you told them that you are a not a native speaker. Let me give you an example:
On Saturday my husband and I were invited to a birthday party in a little village in the North.
One couple (elderly people in their late 60's) sat at our table. My mother-in-law introduced them to us and vice versa, and made a little joke, saying "that's Paul's wife, she's from the very far South". The woman asked me where exactely I am from, so I said that I am German. And all of a sudden I heard her husband say "Isch spresche ein bissen Deutsche". I smiled at him and he continued (in English this is): "My English.. in restaurant, ordering food, good. Ordering drinks okay. But the rest.. very very bad". Both my husband and I starred at him and we did not know whether to laugh or to cry. I smiled and said "Well, ordering food and drink is basically all you need, isn't it. You could still use your hands and feet for the rest. And if nothing helps, draw them a picture". His wife seemed so embarrassed so she tried to take the attention off her husband. She asked me what I am doing in the UK and I said "I work as a Linguist Monitor and translator". In that very moment I could see the man blush

Well that was my experience on Saturday. I am not mad at the man, not at all. Although I think if you're being introduced as the wife of an English man, people could assume that you're able to speak the English language. Don't you agree?
So how about you? Are you fluent in a language but have met people who spoke to you like you were either thick or hard of hearing? Have you ever smiled at someone but thought "Talk to me like to a human being, I am 28 years old, not 5 years old"?
I'm interested in your experiences and remember, it is about all languages, not only English
