  In view of the upcoming observations with the Event Horizon Telescope (EHT),
we present our thoughts on the immediate environment of an astrophysical black
hole. We are concerned that two approximations used in general relativistic
magnetohydrodynamic numerical simulations, namely numerical density floors
implemented near the base of the black hole jet, and a magnetic field that
comes from large distances, may mislead our interpretation of the observations.
We predict that three physical processes will manifest themselves in EHT
observations, namely dynamic pair formation just above the horizon,
electromagnetic energy dissipation along the boundary of the black hole jet,
and a region of weak magnetic field separating the black hole jet from the disk
wind.
