Yes, that totally makes sense! Thanks for taking the time to write it out!
[name_f][/name_f]Now I have a lot more thoughts about this topic that I will share [name_f][/name_f] because I find these things fascinating haha, but feel free to skip over it because it’s wordy lol. Most of it just spilling what’s in my brain 
For the Lost in the Pond guy, I think I was more so surprised that he hasn’t adapted to her pronunciation now that they’ve been married for several years since a marriage is a close relationship. But, of course, it must not bother her because I’m sure he wouldn’t keep doing it if she didn’t like it! [name_m]Just[/name_m] all very interesting to me 
[name_f][/name_f] [name_f]In[/name_f] a genuine way, of course. And maybe it’s easier for Americans to switch to between those sounds, so I absentmindedly assumed it went both ways. But I shouldn’t have made that assumption because I also recognize that with other languages/dialects, certain sounds are hard to imitate or to distinguish for people outside of that language or dialect. [name_f]Or[/name_f] even how [name_m]Harry[/name_m] and hairy are pronounced differently in [name_f]Britain[/name_f], but it’s hard for Americans to notice the difference between the [name_f]British[/name_f] versions of both—I can barely tell if I compare them side-by-side, but I wouldn’t be able to guess which was which if I heard each word by itself. And I think I’ve been exposed to more true [name_f]British[/name_f] media than the average American.
I guess my follow-up question about the Tair-uh pronunciation by Brits would be about other words that seemingly have a similar sound (I say “seemingly” because maybe these sound similar to my American ears, but they could be totally different to Tair-uh to a Brit’s ears!). Question: [name_f]Do[/name_f] hairy and [name_f]Claire[/name_f] have the same -air[name_f][/name_f] sound as the American Tair-uh and Clair-uh? Mainly asking about the -ai-[name_f][/name_f] part because I know that r’s have a very different pronunciation between the two accents, and that it is hard for either country to imitate the other’s -r-[name_f][/name_f] sound. I could also see if transitioning the “-airy” and “-aire” to an “-aira” sound doesn’t transition the same wayAnd I hope these don’t come across as combative or anything like that, but as genuinely curious because I think accents and language differences are fascinating 
[name_f][/name_f] And I also hope my thoughts and questions make sense 
[name_f][/name_f]Side note of another story that's also kinda related to this post haha (and because I find different pronunciations for names and words fascinating!)
[name_f][/name_f]Our daughter is actually Claire-uh, but our relative (~age 30) calls her Clarr-uh even though she’s also American, but because her main association with the name is [name_f]Clara[/name_f] from [name_m]Doctor[/name_m] Who lol! [name_f]She[/name_f] did ask at the beginning which pronunciation we were going to use, but she almost always uses the [name_f]British[/name_f] pronunciation (which I’m fine with because I know she has no ill-will at all about it, and I know it’s not because she doesn’t make an effort. Plus, I love both pronunciations as well as the DW character haha, so it’s extra fine. When we had picked the name [name_f]Clara[/name_f], we actually considered the [name_f]British[/name_f] pronunciation because we loved it so much too! But we decided on Claire-uh because we loved it just as much and felt it would be easier for her since most Americans are not familiar with the [name_f]British[/name_f] pronunciation.
