You have this new neighbor who lives an apartment below you, who lives there for about 5 months now, but you never met him in person. He's very noisy, some days it annoys you and other days you quite like it. Meaning, that his singing is so angelic like, which makes you think he's some angel that came down from heaven. You enjoyed listening to him outside on your balcony. These days, you noticed he hasn't been singing much and plays the piano in a sad tune, when it's usually happy.
