“There are a few people at our side who, despite the intensity of a feeling, manage to have lucidity. People who help us to move forward, giving us the strength we need to close doors that have remained open, doors that for too long have continued to let in expectations and hopes, fears and disappointments. These people can be called true friends.”

Prevale (1983) Italian DJ and producer

Original: Ci sono alcune persone al nostro fianco che, nonostante l'intensità di un sentimento, riescono ad avere lucidità. Persone che ci aiutano ad andare avanti, dandoci la forza di cui abbiamo bisogno per chiudere porte che sono rimaste aperte, porte che per troppo tempo hanno continuato a far entrare aspettative e speranze, paure e delusioni. Queste persone possono essere chiamate vere amiche.
