This still doesn't make sense to me, I fear.

You give one particle that is constantly emitting photons in all directions 
a push due south towards the singularity. You have an observer due north of 
the singularity looking south.  The observer due north will continue to see 
photons coming off the particle indefinitely?

But it's not.

Tidal forces are a difference in gravity gradient between head and feet. 
It's not an absolute number. A sufficiently small pebble would experience 
very little tidal effect regardless of how close to the primary it orbits. :-)
