Hi! I'm writing (or trying to write, at least) this story that's based in UK. I haven't decided on an exact location but I'm pretty sure I'll end up with Wales since I stayed there for a year. The only problem is that I'm not sure how to go about with character conversation. How do I make it believable? The way people speak there, the slang they use, etc, etc. Should all of that be accurate? I didn't stay there enough to learn all of that.
