i can't explain waiting following, its like driving...
You very your distance, you stay to the rear, to the right, never more than a few cars behind. Its all about patientce...percentages...timing.
If you get too close move into their blind spot. If you lose them... just keep moving... hope for the best.
Out in the open distance is subjective, let her ride the horizon... as long as you know her patterns.
The waiting is the hard part. Your mind wonders... thinking what it would be like watching your own life from far way.
If she doubles back never react. What ever you do don't get too close, never meet her eyes.
There's always something waiting at the end of the road, if you're not willing to see what it is you probably shouldn't be out there in the first place.
