Well I hope the Scots don't all hate the English because I'm English and very happily married to a Scot!
The only time I've heard any 'anti England' words was when DH and I were not long married (about 15 years ago) and even those weren't so much anti England as a throw away comment. We went to visit family in Edinburgh and went into an attraction there. The young man operating the ticket stand asked where we were all from. Before I could pipe up, my SIL said she was local, DH was from Scotland but lived in London. To which the young man said 'You're living in London? Why would you want to live in that dump when you're Scottish?' 'Ah, says DH 'I married a Londoner' to which I waved with a big smile from the back of the group. DH and DSiL were pissing themselves with laughter. Fair play to the ticket seller, he was mortified and couldn't apologise enough.
Other than that I've had no remarks of any sort about my or DS English accent.
And I can't understand why Scotland isn't seen as more of a holiday destination. Yes the weather can be bad (as one hotelier in Aviemore said to me when I got back from a walk soaked to the skin having started out in full sunshine 'you get a week's weather in a day here sometimes') but if you allow for that people don't know whaat they are missing.
Edinburgh is a beautiful city - yes it has its crappy bits but so does any capital city if you go off the main track. Most of the squares are gorgeous, Holyrood Palace is a great place to visit along with the gallery next door, the Castle is lovely and Dynamic Earth is one of our DS's favourite places.
Although I said the weather is unpredictable, the last time I went to Loch Ness and then the Cairngorms (staying in Aviemore) I got sunburned. There is nothing like a boat on Loch Ness sailing past Urqhuart Castle when the bagpiper plays. There's a house opposite that I always say will be mine one day (in my dreams). Stunning place. And talking of the Cairngorms, if you've never fed the reindeer on the lower slopes of the mountain, you've missed a treat. That and the sheep dogs owned by Neil Ross - bottle feeding a lamb with a puppy sheep dog at your feet is magical.
And the coastal area between Inverness and Aberdeen needs to be seen to be believed. So beautiful.
Before we were married we did a week in the Highlands (DH is a Highlander by birth). A night in a different town or village. We stayed in rooms in someone's family home, on a farm and in a town house. Never had anything other than a warm welcome.
Yes, sometimes people do support any team but England - but that's up to them. I'm sure the same happens to Scots, Welsh and Northern Irish supporters teams too, it's just more subtle.
I think we live in a great country on the whole. We've been to Wales and Northern Ireland and, again, had no rudeness. Then again I'm not rude to them and I'm not looking to analyse every word or look given to me.
