I am in love with someone who speaks Mandarin Chinese as their first language. Her English is not bad. It's getting better, but it was a struggle at first. Aside from the obvious language barrier, the cultural barrier is the thing that causes most of the problems. I live in her country right now, and I do my best to try to understand why certain things are done and just go with it, but sometimes it is extremely difficult. But it is a challenge that I have chosen!
