Once upon a time there was a composer who poured out melodies for audiences to hear absolutely free of charge. Then, said composer realized composing required being able to stay alive which also had something to do with earning an income and eating. Said composer became a teacher and put away those artistic dreams, thereby saving all those castles in the sky, also known as clouds, for later.
Yet here said composer stands, pouring out melodies for audiences to hear absolutely free of charge. Some things never change.
