i'd help you. but you have to be serious. Not just one or two conversations and disappear. And more importantly, you must have SOMETHING to say. You must monopolize the conversation. Tell a story, talk about family, talk about government, anything.
but remember, I can't help you if you have problem translating something because I do not speak your language. Everything you say must be in English.
I think the problem all you are encountering is that Westerns usually like to associate with each another. They (we're) not very hospitable nor friendly to foreigners. But feel free to disagree with me.
