Some thirty five years ago I was in mainland Europe with my friends Joe and John. We had no maps (nor GPS/SatNav), but we found our way driving around France, Italy Germany and Belgium. Paris of course, Venice, Florence, Sienna, Assisi, Gubbio etc. And Munich, Dachau and Antwerp. We slept in the car; in a tent; in cabins, and once in a while in cheaper hotels. I got very sick in Florence. After Florence we became very silly about the name GIOTTO. We used it as an exclamatory. In Gubbio I bought three little boxes of crayons with the marketing name of GIOTTO, one for each of us - just for fun. The other day I opened a treasure chest box. Guess what I found? My Giotto crayons, thirty five years on.
