It’s a hint that someone needs to leave
That would make it -2
I think it’s more likely that the one person there just died
Ah yes, an anti-person. Anyone who comes in contact with it will be zeroed out of existence.
When the person and anti-person are annihilated is there a release of photons? Or is the energy release more intense?
I believe (what with not being an expert at all) that the energy release upon annihilation is directly related to how positive or negative the person is.
My guess: a count increments upward when the entrance door swings open and downward when the exit door swings. If one person holds the door for a few people but they exit individually, the count gets messed up.
You have to scan your student card on entrance and exit but I think it gets messed up if someone gets put through by the desk staff without scanning.
