While studying abroad in London we stayed in flats that were part of the London School of Economics. They were like dorms with a main desk downstairs and apartments upstairs. Each flat housed three students from our program.
One day I came back to the building and found a phone message with my name on it. Your mum rang, it said. There was nothing monumental about the message or the  subsequent phone call. We enjoyed the inherently British nature of the message.
I still have this slip of paper dated August 3, 1987. Even though I have kept this for nearly 25 years, it seems more poignant and more important that I keep it now.
