In Singapore, we have many HDB flats built close to each other, each densely populated with families of typically between two to four persons. If you are a heartlander, hearing baby cries, couple's quarrels, and loud renovation works, are really not quite uncommon. Even the barking of the dogs or karaoke singings would remind you how close we are living just next to each other. Thus, it is understandable that being a good neighbour includes keeping noise level down. So, what time after must you stop playing the piano at night?
