We are at the park. At the Estacions park in Palma, where small social ecosystems coexist with each other. Now, from where I wait for my bus departure time, I can observe one. It is the ecosystem of the people sitting around the multiple and enormous planters in charge of generating shade. Inside each one, four trees rise, connected by earth and air: their crowns caress and join into a single roof that shelters us all, and the branches tickle each other with lights and shadows, letting the air in. It is a late summer afternoon and since I sat under the shelter of this porch I have stopped huffing, sweating, and swearing. The city seems, for a moment, habitable.
