Me - yesterday and before that, Tuesday.
Yesterday I got on a tube train and sat in the last empty seat in the carriage. I could see the reflection of the girl next to me in the window and thought to myself that she was not unattractive. Then I thought actually she looks like my housemate. Then I realised it was my housemate and I said hi and we passionately hugged much to the bewilderment of the other passengers.
And the other day at lunch I bumped into someone who was in my group in North Korea. Small world huh?
