feels threshold

She began to shut the door. "This is my home. And I'm not inviting you inside."
"Groovy," I said, and stepped over the threshold and into the apartment, nudging her gently aside before she could close the door.
As I did, I felt the pressure of the threshold, an aura of protective magical energy that surrounds any home. The threshold put up a faintly detectable resistance as my own aura of power met it - and could not cross it. If Anna, the home's owner, had invited me in, the threshold would have parted like a curtain. She hadn't, and as a result, if I wanted to come inside, I'd have to leave much of my power at the door. If I had to work any forces while I was in there, I'd be crippled practically to the point of total impotence.
I turned to see Anna staring at me in blank surprise. She was aware of what I had just done.
"There," I told her. "If I was of the spirit world, I couldn't cross your threshold. If I had planned on hurting someone in here, would I have disarmed myself? Stars and stones, would I have shown up with a cop to witness me doing it?"
