What did you do in the dark?

Last night at 8.30pm it was Earth Hour when millions of people all around the world turned off non-essential lights for an hour. I took part in this last year as well but this year I loved their tag line: what will you do in the dark? Well, we had a total Mad Men fest and watched about 3 episodes in a row, lit a fire (because apparently it's Spring yet the wind chill is minus 5...), and snuggled up in the dark.

What did you do?
