This great title from a New York Times bit on the house guest and a book, Host or Hostage - A Guide for Surviving House Guests, by Darlene Dennis.
Harrowing houseguests come in many varieties, from Clueless (often in
their early 20’s) to Aggressively Exploitive, but they share one trait:
an uncanny ability to find hosts willing to place the guest’s needs
before their own — people who become, as Ms. Dennis put it, hostages in
their own homes. Two such people interviewed for this article did so in
whispers, because of guests they were unable to evict.
I just informed the newlywed niece of Providential flight reservations for a post-retirement visit. And I'd love to get out to the Cape while I'm there. But no pressure.
