A cycling-themed dream. I had bought a messenger bag – one of those "first wave" blue and red ones made by Timbuk2 (I think) – and was using it when riding to visit a friend for a weekend. I got caught in a heavy rain storm and took shelter in a shop doorway. The rain stopped, the sun came out and I noticed that it was warm and I was wearing shorts. I was so happy, I swung the bag round in delight – and lots of dark liquid ran out. I looked inside and a bottle of vinegar had broken. Why I was carrying a bottle of vinegar is unexplained (making chips?) but the message is clearly that if you get a messenger bag, be careful how you pack it.
