When we don't want to talk to someone or be their friend anymore, we might say "send them to Coventry!" This is an old saying that comes from a time long ago when people in England would punish someone by not talking to them or even looking at them. This punishment was called "sending someone to Coventry." It was meant to show that the person was not liked or trusted by the other people. Nowadays, we usually just use the phrase as a way to say that we don't want to be friends with someone anymore.
