I know now that the dress I wore to my best friend's wedding was inappropriate, and since I realised, I've been quietly cringing. I even did a reading at the church in it (don't ask how I didn't realise at the time it was inappropriate - I was just an idiot, I suppose, and genuinely it didn't cross my mind that "dress for wedding" and "dress to go out in" differed).
WIBU to apologise after 20 years, or will it just remind her what a nob I was?!
NB I know the DRESS was U, but would a 20-year-old apology be?
YABU - you shouldn't apologise, it will only remind her. Or you don't need to.
YANBU - yes, apologise
