Language and grammar is a special feeling in my brains,I like international contacts to hear sounds(info) of people who grew up in other social surroundings,cultures.
Sometimes it is a weak point of mine and I realize that there are people who are annoyed when I make a remark.
But sometimes it is a challenge for me,how far can I go before there comes a reaction,because of a culture,way of behaviour,self-command,etc!
