Eri knelt down slowly and thought about her world. The one with the solid ground in which she had stood all her life. Would that surface break apart one day? And when it did, what would happen to her? Perhaps she would end up floating aimlessly in a vast nothingness. Her feet never touching the ground again. Her hands never finding anything to hold onto.
I've been trying to edit this for about an hour. It's like a chess dilemma I created myself. I can't replace ground with surface because I'm already using it in the next sentence. And it seems like feet never touching the ground is the most natural way of saying it. I think feet touching the soil and feet touching the land sound strange.
Does anyone have a simple, effective way to solve this?
