yesterday

I was sitting in my car.
Waiting for the light to turn green.
I looked ahead of me and felt a tinge of panic when I saw the car on the other side of the intersection. I looked around fearful that I was either on the wrong side or going the wrong way down a one way street. The driver of the other car appeared to panic as well. I felt relieved when I realized it wasn't me. The other car was going the wrong way down the one way street.
Then I wondered...
...what will happen when the light turns green?
