Today when I was waiting on the cross, several big buses and trucks stopped before me, the line of sight was cut, after almost half an hour, nothing moved.
I don't know what happened, then became a little anxious and nervous. later when the Big ones moved out my eyesight, and I can see the situation clearly, though I still need wait at that moment, I was calm down.
I ask why to myself later, realized that it's important there's a clear vision when you do or wait for anything.
Same thing applies to the relationship. (left or right, finally turn back to the relationship:))
