This is a personal observation, and obviously not necessarily reflective of the 'wider' mood in the UK [and beyond], but amongst my friends, family, colleagues and acquaintance, and amongst my Social media 'friends', there has been a marked 'change of tone' of late.
Previously 'those that cared' or were interested in the Wedding [a majority], were excited and full of anticipation, and 'happy' for the couple..
Now they are weary and WARY, wanting it 'to be over with'...There is a palpable sense of unease and uncertainty, even [amongst some] of foreboding...
None of this is the fault of of the couple themselves or the BRF, and less to do with the 'minor' Markles [most have NO idea who Samantha even is]. It is the antics of Markle Sr who is responsible for this obvious pall.
I'm old enough to remember quite a few BRF weddings, and, although [in retrospect] the 'all was not well', in some cases, I have never registered any level of disquiet prior [even] to the ceremony itself... Today, there IS.
It is very sad, that one individual [and SO close to a principal party] as contrived to 'take the shine off' what ought to be a joyous occasion...
