If you can do it, conversation is the best way to go. During lunch at work, I was introduced to someone's mother from the Netherlands. I saw her come in, and I knew that she would be brought over. I spent several minutes trying to think of what to say. Then there was the introduction, "...He speaks Dutch!"
"Ik ben wachten de nieuws van NOS."
It wasn't a traditional greeting, but her face lit up. She went on about how she liked the place where we were. To buy time to think of something else to say, I interpreted her remarks to others around us.
After that, I kept thinking of things to say. It was a huge breakthrough. I had hoped to see her again, but the rest of her visit was taken up with other places.
