I'm Australian and my husband is American - two fairly similar countries you'd think, but there are still plenty of things that we argue about that are different! It can definitely pose some problems I think, because of what you've grown up accepting as normal -- so I try and bear that in mind. Every couple faces some challenges, whether it's different cultures, races, religions, even different hobbies can sometimes bring about arguments. As long as you're both on the same path overall I think it's all okay in the end.
