I have spent this weekend in BS5 and it has been strangely interesting in a niche sort of a way, with plenty of activity in unusual things. My friend Andrew is here, preparing for his imminent art exhibition in London. I accompanied him to my local post office to send 45 packages around the world promoting his show. We chatted to the post office fella about stamps, envelopes, weights, rates and shipment times. He was geekier than we were and had some serious interest in envelopes. Who knew it was such a topic of delight?
