I can imagine how this thread is going to go, so I'll preempt it with:
1). Yes, I know I should have stayed away from all social media, and
2). Yes, it really is a first world problem.
But lots of people watch telly on catch-up and I was looking forward to watching the final with a bit of ironing later. Facebook is for posting pics of your kids and kitten videos. Not for spoilers dammit.
And it's not as if posting your congratulations to the winners is a scintillating read or anything.
Grrr!
