London so far

I've been here for about 5 days now, and as a true connoisseur of culture, I can report the following:

• I do feel a little self-conscious anytime I speak up because unlike when Jamie comes to the States and talks and people swoon, my accent is probably an affront to their pretty little English ears.
• And side note, who knew the word connoisseur was so hard to spell?! My iPad never once figured out what I meant as I made guesses (connesuer?), so I had to Google it.
• I navigated the post office and bought some international stamps. Now that I have them, would anyone like to be pen pals?
• I've committed to a gym. Well, not a proper gym, but a "leisure center", and from what I can tell, it's similar to a YMCA. The proper gyms I did check out were managed by people with names like Cleopatra and played music louder than any club I've ever been to and were full of people doing things my body just won't do. So when we walked into the locker room of the leisure center there was an old, naked woman drying off and giving me the stink eye, I knew I'd found my home.
• "And Bob's your uncle." I'll asked Jamie to write up a short definition of the antiquated but still-beloved term, which I will post once he responds. 
• The Brits think we Yanks eat meals obscenely early. Well, my particular Brit does. Evidently lunch at 12pm and dinner at 5:30 (17:30) is just not a thing here (such a disappointment, right?). I am going to poll more people to find out if this is his personal preference or a more consistently-held belief. Tell me, friends. Is this to be my crusade? Reasonably-timed meals in the motherland? Or, are there more worthy causes to pursue (like integration of "y'all" into everyday speech)?
• I've filled out a few forms, and I have, without fail, written them in MM/DD/YYYY format. Turns out that's "wrong" and you list the day first, so I have to cross it out and start over. I couldn't help but wonder - does it still only take 21 days to change a habit if it's a 31-year-long habit?
• Eggs at the grocery store aren't refrigerated! If you want proof, I'll text you a pic.
• Americans may have the reputation for being the fatties, but the Brits effing love their chips (crisps) and take just about anything and turn it into a flavor. Consider, as some examples, the following bags I saw in the shop: Crispy Bacon & Maple Syrup, Hoisin Duck, Tomato Ketchup, Worcester Sauce, Marmite, and Prawn Cocktail. 

I'll leave you with that.
