Dear Student,
language is the basic of every social life arround the world. Without enough understanding and confidence of it`s usage, you will never become what you hope to be abroad. Feelings and culture are imbeded in words and sentences. To understand someone in the other language, at first you need to grasp their every day culture.
It is a step by step task but stacks up pretty quick.
I hope to be a stepstone to cross the troublesome time of understanding for you.
See you arround,
Matthäus
