Go Back? Really? You know, not only one on this forum is a brit. But we all know, you have the best people, the best cities, the best of everything. That´s why you have the mad expression "best of British". Almost same mad as "hunky dory"! And by all means, do not tell people that you call them. just say "I give you a bell". Still, you have not understood that Graham Bell did not invent the phone. It was Edison. Wonder how long time it´s going take to change to "I give you an edison".
Only that kind of abuse of English will make me stay away from UK, among many other things your arrogant society have to offer. I am amazed that a Thai woman can have the wish to move to London. Will probably be like 80-90% that tried. They will be back here telling horrible stories for a lifetime. ????
