Translation of Unbesiegbarkeit

I love it during vacation and being in the mountains. There it is like being in a dreamland. Everything is covered with snow and is bright and white. You get up at eight in the morning for breakfast.
I'm so happy that you wrote to me and I miss you! We are doing great. We have settled in very fast. Luise is going to her kindergarden, Sofia to University and I'm going to work driving my car every day.
I rarely heard someone speaking so bad about his nation, but again, it wasn't my business. We closed the lights at midnight and hoped for a few hours of sleep. The train shaked and threw us around in our beds.
