When I was quite small, my parents gave me a stamp collecting kit. There was a book to put your stamps in, a magnifying glass, a special little gauge to measure those holes along the sides, and a bag full of used stamps from around the world, as well as a guide book explaining that my bag of stamps was worth nothing. I still remember the excitement with which they handed it over, having collected stamps themselves when they were younger. “This”, I remember thinking, “blows!”
