ELI5: If me and another person are looking in a mirror and I make eye contact with his reflection, is he making eye contact with my reflection also or looking at something else?

The angle of reflection is equal for you both.  So you're both looking at each other.  With a little thought this will be obvious.

You'll notice that movies will sometimes cheat at this.  A girl will be admiring herself in the mirror but in actuality she's looking at the camera.
