A 'soi' in Thailand is a narrow street or alley. They can wind through various communities and business districts. They can be shortcuts to and from work or they can be mazes where you can get lost (especially for tourists). Some sois are quiet during the day and dark at night. Most, however, are lively networks teeming with food stalls, wet markets and small shops and houses. Busier sois are "mini carnivals" where all your senses ares stimulated. This video shows you a typical night on the "big soi" that runs by my wife's family's home.
