Seriously, What's the Point?

Part of my job involves calling a large amount of people and talking to them about my client's products. In the last 3 days I've noticed a strange trend in the many voicemail messages that I've heard that say someting like, "Hi I'm out of the office for most of this week but returning Thursday, May 25th..."

Is that for real? Why would you take three days off, come back to work for two days* and then take another three-day holiday beginning the weekend? Why not just take the whole week off and get, like, a mega 10-day holiday? Makes no sense to me.

* and by "two days" I of course really mean one day because nobody in the history of employment gets any work done the Friday before Memorial Day. Stop kidding yourself.
