Hmmm, I think a lot has been different in 10 years.
First:
Politics have been crazy in 10 years.
When I came we had a Labour government and there's been lots of change through the Tories. (This is not change that I see as good, but I'm not into Tory policies)
Brexit.
There's been mad political upheaval in Scotland with the SNP and Scottish Independence stuff.
At the time, George W. Bush was a huge embarrassment and made the US look like buffoons, but man, if only we knew that we'd get Trump and be the laughing stock of the world....
Second: Food - Mexican food has become huge in the UK (well not near me, but everywhere else it seems). And you can easily find Old El Paso and Wahaca stuff in the supermarkets. Also lots of American sweets and cereals and whatnot are found in supermarkets too. We used to discuss how to find a good peanut butter, but you can find all kinds of peanut butters now. You can find BBQ sauces and liquid smoke as mainstream items. Lots and lots of choice, even within 10 years. Pumpkin patches and pumpkins in supermarkets.
Third: Drink - Craft beer, really. Finding craft beers in supermarkets. Gin has become huge in 10 years,as well. Scottish craft gin is booming. Pumpkin Spice Lattes. Nope you couldn't find them. And then one day you could.
Fourth: Clothing. 10 years ago we discussed the limited options with plus size clothing, anything over a size 16 was hard to find. Now it's really pretty easy to find plus size clothing. Would always love a better choice, but it's amazing when you think you won't find your size in a shop and it's there now.
Fifth: TV. Pretty easy to watch shows from the US with Netflix, Amazon,and other Sky Channels. Not lots of waiting now.
Sixth: American football. Games played regularly in the UK and the other day I saw Patriots, Bills, Dolphins, Packers, Cowboys, and 49s hats in a sport shop.
Seventh: Facetime/whatsap/facebook messenger/skype The iphone was brandy spankin new. Smartphones were just starting to gain traction. Facebook didn't have a messenger option back then. I skyped my family off my laptop. It was amazing, but still slow and fuzzy in pictures. Ended up needing to still dial off landlines alot. Wouldn't have done it off a mobile phone. Now, in even remote parts of Scotland, you end up finding a 3G singal. I can call my family whenever/however through all these apps. It makes the world smaller.
I'm sure there are other things I have forgotten as well.
