It's almost like, how technical do you want to get, James Santoro? Of course, photons don't just bounce off the surface of a mirror. They undergo a quantum interaction with one or more atoms that make up the mirror. There is no definite "angle of incidence, angle of reflection," only a set of probabilities for where the photon might end up. Billions of photons will end up where our common sense would expect, but a significant number of others will not. Occasionally, one will even tunnel through the mirror....
