Sitting on a bus in front of two women speaking in French, talking about everything, they eventually came onto the subject of "Les Anglais". I don't understand French very well - but I was annoyed. It's not like we can't understand when we're being spoken about. At my stop, I prepared to scowl at them, and saw they were black (instead of white as I assumed) and somehow I felt that talking about "Les Anglais" was no longer so insulting. My assumption about their conversation changed - my assumptions about what they were saying and why they were saying it...
