That was a nice way to put the the special theory of relativity without getting into the math. Although the paradox bit (at the end) resolving it with the Doppler effect is just not right...

No. It's just a matter of perspective. Kind of like the grass is always greener from the other side.
If you were in a box moving at a constant velocity, (say on the Earth) there'd be no way to tell if you were moving or not, unless you had a window (assuming the box didn't jostle around like in a car or train).
Or we were in space and we were both moving at a constant velocity in opposite directions, it would seem from my point of view that you were traveling in one direction with a velocity (and I was holding still) where as from your point of view I was traveling in the opposite direction, with the same speed, but you were holding still. This is assuming you couldn't see the stars...
