In the following sentence:
To fill in the blank, I picked up 说着说着, but the correct answer was 躺着躺着.
The other two candidates were 跳着跳着 and 走着走着, and I even think these are correct as well... because the electrocity can suddenly stop even if you jump, walk, speak, or laid down.
Why is 躺着躺着 correct here? And what is the reason the verb + 着 is repeated here?
