If you're staying in an unfamiliar city, it can be an absolute blessing when a friend takes you into their home -- so much so that it's easy for a weekend trip to turn into a month-long getaway (from your life). But hey, if they didn't want visitors, they shouldn't have gotten that Karlaby sofa-bed from IKEA, right?
With that in mind, you should beat a hasty retreat if you start to recognize any of the following signs:
1. They heave a heavy sigh upon encountering you in the morning, as if they were hoping you'd magically left in the night without saying goodbye.
2. All those little quirks of yours, the ones that made them laugh so much at first, now result in awkward silence, a change of subject, or your friend fake-remembering to do something and leaving the room.
