Gosh, I remember it completely differently. I was a teenager and was appalled she was being married off so young. That engagement interview was so awkward, it was soooo obvious he didn't love her and it was all doomed.
We were all willing her to walk away, but as her sister famously said 'it's too late now, Duchy - your face is on the teatowels".
She had no one looking out for her - a dysfunctional family and no social media or phones to contact anyone like her mates when she was under virtual house arrest in the palace in the days before her wedding.
I remember me and my friends and actually most people I knew were agog at the spectacle, the lamb to the slaughter.
We willed her to be happy but we knew it was going to be an absolute disaster.
We weren't all simpering royalist thickos in the 80s you know. (Just like people now say 'oh, pervy DJs, sexism, teen marriages etc, well it was the norm back then.' Well it did happen just like it still does today - but that doesn't mean we thought it was OK!)
