due to visiting different contries, and workin with multinational crew, i've got understanding about some culture things. When i'm speeking English, i'm also trying to change mind on it, cose its a different manner ot building sentences, thats why ro understand berrer touch some times a little bit culture. There is nothing special, its also possible to learn if u have free time, and you put some target in mynd)

I wish also to find time for Maughm, its also part of Your life.
