On a well traveled road that is intersected by another road and a stop light, underneath a bridge, there are two lanes of traffic. When you arrive under the bridge at the stoplight, there is only one lane. which means you have to merge. When traffic is light, most travelers remain in the right hand lane. but as it begins to be lunch time, or rush hour, there is nothing left to do, but to inhabit both lanes. For if we all chose to travel in the right lane, we'd be backed up two or three lights back, and those traveling in the perpendicular direction would be hampered in their travel.
I've observed the behavior at this traffic light for a while, and I've noticed that traveling in the left hand lane amounts to the same thing as traveling in the right hand lane. When you travel in either lane, and you reach the bridge where the road narrows and turns into one single lane, people inevitbably take turns. No one remains steadfast in their belief that cars should be in one lane or the other. They realize that in order to move ahead, and get where each is going, that each, must at one point, submit. If you are already in the right lane, you may have to submit to the person on the left. you may let them go first. If you are on the left hand lane, you may have to submit to the person on the right, allowing them to go first. When you do, it is inevitably your turn next, and the person in the right hand lane just knows this.
The merging of traffic is much like the weave of fabric. Over under, over under, over under. Left, Right, Left, Right--many strands merging together, taking turns, become one piece of cloth.
The flow of traffic becomes effortless when we travel in our own particular lanes, side by side, and arrive at a point where we surrender.
Without surrender, we'd merge into each other, not around each other.
