In most languages, greetings are usually followed by "small talk".Small talk means the little things we talk about at the start of a conversation.In English-speaking countries people often make small talk about the weather."Nice day,isn't it?""Terrible weather, isn't it?"

But there is something special about small talk.It must be about something that both people have the same opinion about.The purpose of small talk is to let both people agree on something.This makes meeting people easier and more comfortable.In the UK people usually agree about the weather, so it is a safe topic for small talk.But people often disagree about religion or politics so these are not suitable topics for small talk.The topics for small talk also depend on where the conversation is taking place.At football matches, people make small talk about the game they are watching."Great game,isn't it?"At bus-stops people may comment on the transport system. “The bus service is terrible, isn’t it?”
