Yeah, there are differences, but only if you really try to seek them out. I'm originally from Manchester, born and lived there for 38 years. Moved down to Poole in Dorset over 10 years ago, and at first I found probably about 80% of the people I met quite curt, bordering on rude. But as time has gone on, I got used to people here, I found their attitudes have softened, unless I was just mixing with the wrong folk in the first place. Lol. Anyhoo, I think, as you get used to each other, you often find that the way you first looked at other people's perceived personality, ended up being a mis-representation of how they actually are.
And if you can understand any of the absolute drivel I just wrote, then you're a much better person than me... lol. My head's an absolute she'd today, but I hope you all caught my drift. 🙃
