Languages are all funny when you have to swap between them. My mom used to confuse people at stores when we just arrived to Sweden. In South America when you go and buy something at a store, they normally ask "Something else?" before you pay and of course my mom would answer "No" in such a situation. In Sweden they have a similar question which translates to "Is it OK with all this?". My mom would of course answer "No" and get very confused looks and questions about what else she wanted ;-)
