Southbank, at an eastern bend in the Thames, is the center of British skateboarding, where thecontinuous crashing of skateboards left your head ringing. I loved it. I soonmade friends with the local skaters. We spoke our own language. And myfavorite: Safe. Safe meant cool. It meant hello. It meant don’t worry about it.Once, when trying a certain trick on the beam , I fell onto the stones,damaging a nerve in my hand, and Toby came over, helping me up: Safe, man. Safe.A few minutes later, when I landed the trick, my friends beat their boardsloud, shouting: “Safe! Safe! Safe!” And that’s what mattered—landingtricks, being a good skater.
