When is it rude to speak a language that at least one person who can hear cannot understand? My family and friends generally are of the opinion this is rude behavior but I noticed with some new roommates and some answers to my previous questions some people do not have the same opinion?
I have a couple roommates from Poland that often speak a different language that other people can't understand. They do this in the common areas, even when other people are near them. I was very surprised to see that the Polish roommates invite over guests who can't speak Polish and speak it in front of them. To me this is very rude because it's excluding someone you invited. This has happened on multiple occasions and it's not a brief thing but lasts for minutes.
Is it cultural? Do some people not consider this rude? Obviously there's varying degrees but to me it certainly crosses the line when you invite a guest and in front of them speak a language they don't understand and the guest is left just sitting there awkwardly. I'm very curious how they interpret the situation and wonder if there's a way I can ask them what they're thinking?
I know it's difficult to learn a language, but one thing that makes this different from what I've experienced in the past is that they go straight into the other language where other people tend to try in English and then use their native language after having too much difficulty in English. To put simply it seems they don't even try English, though they speak it well when they do.
