Multiple-choice question: When you are leisurely cycling alone and a fellow rider passes you, what do you do?

A. Continue to leisurely ride your own.

B, NND, dare to pass me, pass back immediately.

Today, I was in a bit of a hurry when I rode outside. I kept my speed at about 25 and passed a dead flying brother in front of me. In a few minutes the dead guy was back on his feet. A few moments later, I saw the brother in front of me having a close encounter with an electric car. Every time you pass someone on a bike outside, that person will try hard to pass you back, especially if you see a road bike and a mountain bike...
