I stepped across her threshold. Something tugged at me as I did, an intangible, invisible energy. It slowed me down a little, and I had to make an effort to push through it. That's what a threshold is like. One like it surrounds every home, a field of energy that keeps out unwanted magical forces. Some places have more of a threshold than others. My apartment, for example, didn't have much of a threshold it's a bachelor pad, and whatever domestic energy is responsible for such things doesn't seem to settle down as well in rental spaces and lone dwellings. Murphy's house had a heavy field surrounding it. It had a life of its own; it had history. It was a home, not just a place to live.
I crossed her threshold uninvited, and I left a lot of my power at the door as I did. I would have to really push to make even the simplest of spells work within. I stepped inside and spread my hands. "Do I pass inspection?"
