In general, correspondence through an agent is not the best way to communicate, it is. But not the worst either. Imagine we were in the Middle Ages. When the pigeons were sent with letters) the same agent just imagine that there is a dead person at all and messages come once in...eee... once a day. In the best case!

A pigeon can confuse everything and fly into another window. From here came the phrase "sorry, I confused the windows"

Well, or any other force majeure, will fly tired and fall into the river with the crocodiles. They will save him and courageously take on the courage to deliver the letter. You open the window and there is a crocodile in the teeth of paper. The eight-floor bedroom was stunned. And you will naturally shout "Y@pthumb!" and you will shut up the fork and it will fly down.
