Indeed.
There is always a back door.
The most deadly intruders don't come through the front door. Only a dumb as FUCK intruder would do that.
The one who bursts into the front door knows he has been seen but he feels invincible. The one who sneaks around in the dark knows that he is vulnerable as FUCK and must not be detected.
The Only question left is "who's watching
the Doors and what are they going to do about it?"
We have it all
Payback is a Bitch
Bad Timing.
