Good job it's the weekend then...Hope you enjoyed your nice long sleep in!
When I was a teenager, one of my friends did the reverse and put her alarm forward in the autumn, went off to church at what she thought was the right time, and wondered why no-one else had turned up...
I have a magic radio controlled alarm clock that resets itself for me.

Seriously. I didn't really put clock back, as I am a bit more savvy than that and put clock forward before I went asleep.
But could have been a problem if I had taken note of advice in email from DCUK telling us not to forget to put clocks BACK and we had extra hour in bed. Especially as I was in hotel and could have missed check out. Bit of sloppy mistake by admin!
