"Interveniency" is a word in ENGLISH

A new business was opening and one of the owner's friends wanted to send flowers for the occasion. They arrived at the new business site and the owner read the card; it said "Rest in Peace". The owner was angry and called the florist to complain. After he had told the florist of the obvious mistake and how angry he was ,the florist said. "Sir, I'm really sorry for the mistake, but rather than getting angry you should imagine this: somewhere there is a funeral taking place today, and they have flowers with a note saying, "Congratulations on your new location."
