The four stages in a bike riding career

1) No other cyclist is allowed to pass you or even to linger in your slipstream. All are vanquished.

2) You can confidently hang with anyone else you see on the road, as long as they don't mind your drafting off of them

3) You realize the innate value in finding and maintaining your own personal pace on rides

4) Cyclists no longer blow past with an "on your left", but rather, slow down to say, "it's so nice that you still manage to ride!"
