Small talk is a casual form of conversation used to reduce awkwardness in certain social situations. It is common between strangers and acquaintances and typically involves discussing safe topics like the weather, current non-controversial events, sports or entertainment. Small talk occurs in places where people are waiting like doctor's offices, public transportation stations, queues or social events. Its purpose is to fill time, break uncomfortable silences or be polite. Common conversation starters include commenting on the weather, local events or making benign observations about one's shared circumstances or surroundings.
