I'm thankful for her help Mari attended a two-day political meeting at Humbolt University in Berlin and stayed two nights at my place. After searching a Japanese restaurant in the center of the city in vain, we went to explore the city center a bit and had a really quick lunch. I really enjoyed her company during these three days. We also cooked and had dinner together. Mari helped me a lot with my Japanese. I'm really thankful for her help and patience. She taught me some really useful expressions such as "構いません" and お世話になります. All in all, this was a really good experience as I felt comfortable with her right from the beginning.
