While I am working out what to say about the experience of being with some of Colombia’s displaced communities, permit me a word or two in praise of denim. The final week of our month in Cordoba, I wore my jeans for 7 days in a row, 4 of them on a construction site. In that time I helped to dig a 1.5-metre-deep hole, sieved sand to make cement, mixed cement and laid bricks, some of the time on rickety scaffolding. To get to where we were working (building toilets in a displaced community) we had to travel about 20 minutes by motorbike, a journey that included having to splash our way through two huge puddles. And my jeans didn’t get dirty! They just changed colour. So hail, denim, king of hard-wearing, dirt-resistant fabrics. I salute you.
