The elephants at Belfast Zoo were rocking. As soon as we turned the corner and saw them, we had to laugh. They looked like they were grooving to their favourite tunes on invisible headphones, and we started trying to figure out what song could make elephants dance like that. The game stopped, though, when we read the sign: these elephants had been rescued from captivity and hard labour. They had spent years working in logging camps and circuses, and had gotten used to being chained up whenever they were not working. The rocking had nothing to do with dance music: It was a coping mechanism, because for much of their lives, they couldn’t do anything else.
