+Nei giardini che nessuno sa - Renato NULL

+Senti quella POST ruvida
+Un gran freddo dentro l'anima
+Fa fatica anche una GET a scendere giù
+Troppe await dietro l'angolo
+{success: true} che non ti appartengono
+Questo OAuth inconciliabile gioca contro di te
+
+Ecco come si finisce poi
+In catch e console.error noi
+Spettatori malinconici di j-j-javascript impossibili
+Tanti bonus rimandati e gia'
+Response vuote da un'eternità
+Quella throw che non sai cos'è
+Solo lei non ti abbandonerà... mai, oh mai
+
+Ti darei i sorgenti per far fetch come non sai
+L'energia, l'allegria per yarn start e yarn run dustc
+Dirti due, sempre due-cento e farti eseguire
+Dove vuoi, dove sai senza più quel JSON sul cuore
+Nasconderti gli errori, quel server node sul tereh-rminale
+Curarti le ferite e poi qualche log in più per testare
+E poi vederti terminar e poi vederti ritornar ora
+Dimentica, c'è chi dimentica distrattamente un for una domenica
+
+E poi silenzi
+E poi silenzi
+Silenzi
