Yes, I´ve learned the language in order to be able to communicate with people. If you son would like to visit Germany, it is also a great choice - Germany is a country with so much history (and you should make no worry - it is a very safety country), beautiful cities, culture, etc.
Well, when I travel for 10 - 12 hours I just try to sleep, I watch some film, and eat :-)
Yes, fortunately I had the opportunity to visit other countries - I and my husband love to travel, get to know other places, cultures, etc.
Where do you come from? In which city do you live?
