Well from the Brits: You don't give a crap about America's independence day? Well think of this, had we not split off, everything that went right with the last World War wouldn't have gone that way and you'd all be speaking German, assuming you exist by not having your parents eliminated. While you contributed a massive amount to the allied victory, remember that without lend/lease you would have been overrun. So don't shrug off the 4th of July, because us Yanks are still here for you, and we know you'll still be there for us.
To the Brits: Well you gave us Yahtzee, Rowan Atkinson(love Black Adder), Hugh Laurie, the Beetles, and way too many more to list. You had some pretty progressive ideas back in the day, my oldest NA ancestor is a bastard son of your nobles, he sent the young man off with some money, which let the guy get some land. So I and my massive far extended family name exist to day because of you all. You founded our colonies, which gave lots of people the chance to own land when they never would have other wise. Those same colonies turned to rebellion, but as a testament to both of our good nature, we reconciled and became allies. Britain hosts many of the nicest and most soothing accents on the face of the earth. But most of all, thank you British folk, for being some of the nicest, yet most honest, folk I could ever meet. You speak your minds, but have the sense to not be too harsh, and in my experience I've met few people with such honestly good hearts as Britons, even if you are a bit on the salty side... Which I find actually kind of charming.
Also on a personal note. I worked in a Hotel Casino here in Reno, Nevada and it was several groups of Brits who went out of their way to make sure I got a nice tip. I worked in a department that generally didn't take tips, but it was you, the British tourists who went out of their way to convince my Manager and supervisors at the time to let you tip me, I'm not going to forget that. It's hard in today's world to find such decent folk.
So I'll crack a Samuel Adams Rebel IPA on the fourth in salute to Great Brittan, the nation that helped found my family, showed me great people, and that gives me more smiles than most any other nation. God save the Queen.
