Well, you probably have received an automated out-of-office reply mail at some point in life. And maybe you have created one yourself already. Normally it’s just a sentence or two, saying "I’m not here, I’ll read your mail later." Here is one I received today:
"As you read this I might be sunbathing in the Andalusion sun, eating tapas or maybe reading a book. I will be back in the office on the 12th of September and will try to get back to you asap."
Just the though of the beach and tapas kind of relaxed me already, so this is definetely one of the more noteworthy messages.
